A.  BIOMETRICS

 

Description

 

Biometrics is an automated method of recognizing a person based on physiological or behavioral characteristics such as fingerprints, speech (voice), face, retina, iris, handwritten signature, hand geometry, and wrist veins.  Biometrics address the need for authentication, the process of identifying an individual, replacing or augmenting verification based on a username and password.

 

Biometrics can be used in identification mode wherein it identifies a person from the entire enrolled population by searching a database for a match. It can also be used in verification mode wherein it authenticates a person's claimed identity from his/her previously enrolled pattern. Biometrics offers some unique advantages because identification is based on a person's intrinsic part. Tokens, such as smart cards, magnetic stripe cards, physical keys may be lost, stolen, duplicated, or left at home. Passwords may be forgotten, shared, or observed. 

 

Applications

 

In the Philippines, biometrics would most likely find first application in providing verification and authentication for financial transactions (bank loans and social security claims) and limiting access to high-security areas like military establishments and sensitive government buildings. The United States – the US government in particular – currently uses or has proposed to use biometrics in the following ways at the Federal, State, local, and foreign office levels.

 

§         Electronic and Physical Access Control. One use is to provide robust authentication for access to computer systems that hold sensitive information used by the military services, intelligence agencies, and other security-critical Federal organizations. Physical access control to restricted areas is another key application. There are many law enforcement applications, mostly for fingerprint recognition, at the Federal, State, and local levels. Other law enforcement applications include home incarceration and physical access control in jails and prisons.

 

§         Fraud Prevention and Detection. One of the most extensive applications of biometrics in the U.S. is for entitlements. Fraud in entitlement programs is estimated by the General Accounting Office at over $10 billion per year. Pilot programs in several States have demonstrated dramatic savings by requiring biometric authentication for applicants for entitlement benefits.

 

§         Commercial. There are also significant commercial applications of biometrics, principally in financial transactions like use of Automated Teller Machines (ATMs), credit or debit cards, banking by phone and through the Internet, and buying and selling securities by phone or through the Internet. Biometrics is also being considered to reduce or prevent fraud in the use of cellular telephones, which is estimated to have reached over $1 billion a year, and phone credit cards. There are also commercial applications for computer access control, access to web site servers, access through firewalls, and physical access control to protect sensitive information.

 

Current Applications

 

The following are some specific applications of biometrics in other countries:

 

 

Immigration and Naturalization Service's (INS) Passenger Accelerated Service System (INSPASS)

To provide prompt admission for frequent travelers to the US by allowing them to bypass the personal interview/inspection part of the entry process. It uses hand geometry to verify the identity of the traveler at an automated inspection station.  Current installations: John F. Kennedy Airport in New York and Newark International Airport in New Jersey.

CANPASS

The Canadian version of INSPASS, it uses a fingerprint biometric, rather than hand geometry, for traveler verification. The goal of CANPASS is to ease the transfer of goods and people between the US and Canada.  Currently in use at the Vancouver International Airport.

Automated Fingerprint Image Reporting and Match (AFIRM)

Installed in 1991 in Los Angeles County, California, AFIRM was needed to reduce fraudulent and duplicate welfare benefits. The fingerprints of new applicants for welfare benefits are checked against a central database of prior claimants. Within the first 6 months of use, the county saved $5.4 million dollars, and the savings have been growing ever since. The system has been so successful that San Francisco, Alameda County, and Contra Costa County have installed AFIRM and check new claimants' fingerprints against existing recipients in these locales.

The Colombian Legislature

The Colombian Legislature uses hand geometry units to confirm the identity of the members of its two assemblies immediately prior to a vote. The voting has been conducted this way since 1992.

 

Several Federal, State, and local government agencies have purchased biometric systems.  The Defense Advanced Research Projects Agency, Drug Enforcement Agency, Department of Defense, Department of Energy, Department of Public Safety, Department of State, Federal Bureau of Investigation, Federal Reserve Bank, Hill Air Force Base, the Pentagon, and the US Mint have approximately 250 biometric devices with 13,000 enrolled users for access control applications.

 

The following are some planned applications of biometrics in the US:

 

California, Colorado, Florida, and Texas Departments of Motor Vehicles

Efforts are underway to establish biometric-based screening of drivers. California records thumbprints digitally in its database.  Colorado and Texas record fingerprint images on their drivers' licenses. Florida is considering this idea. The goal is to eliminate license tampering or faking.

Government Accounting Office's Electronic Benefits Transfer (EBT) Task Force

Inspired by the success of the AFIRM program in Los Angeles County, the US Government plans to disburse Federal Government benefits (e.g., retirement, social security, welfare) electronically through ATMs and point-of-sale terminals. It is estimated that $110 billion in Government benefits could be transferred onto and debited from access cards in this way. Initial plans are to implement fingerprint identification at the benefit enrollment phase. Fingerprint identification in the benefit disbursement phase is also under consideration to eliminate potential extensive losses from the abuse of lost or stolen cards.

FBI's Integrated Automated Fingerprint Identification System (IAFIS)

IAFIS is designed to electronically replace the horrendously outdated, mostly manual fingerprint identification system that requires paper-based fingerprint cards, postal submissions of the cards, and labor-intensive searches. IAFIS would replace paper-based fingerprints with electronic ones. Requests could be submitted and fingerprints could be searched electronically. The goal is to reduce response time to a requesting agency from the current 10 weeks to 24 hours.

National Crime Information Center 2000 (NCIC 2000)

Biometric information, such as those contained in the signature, face, and fingerprint, will be used in an automated system. Patrol cars will have the capability to capture fingerprints and eventually relay the information to local, State, and/or Federal Automated Fingerprint Identification Systems (AFISs). The goal is to have the new and improved system fully operational by the fall of 1999.

 

Considerations

 

The system is expensive. It is not only the initial cost of the sensor or the matching software that is involved. Often, the life-cycle support cost of providing system administration support and an enrollment operator add a lot to the initial cost of the hardware.

 

 

Prognosis

 

Biometrics technology has not attained enough maturity to merit definite inclusion in the GISP. According to the Biometrics Consortium, the only available information on biometric devices is often just a sales brochure. The performance claims in the sales brochure may not hold true for a given device in a given application. For example, a device that measured 0.3% equal-error rate in a lab was found in the field to have a false-rejection rate of approximately 25% (at an unknown false-acceptance rate). While a change in this device's threshold between the lab and field tests might explain the difference, it is more likely that the 0.3% equal-error rate was measured under unrealistic conditions.  Establishment of an independent evaluation center to test the maturity, reliability and repeatability of a biometric device was expected by the end of 1996.

 

While the reliability of biometrics as a means of authentication is increasing as the technology matures, its price remains prohibitive. Substantial investments are required to set up, operate, and maintain the necessary technological infrastructure. Most, if not all, components would have to be sourced abroad. Expectedly, the major cost after initial investment would be in maintenance and technical support from other countries, particularly the US.

 

However, given the rapid development in information technology, it is not inconceivable that within the 5 year timeframe of the GISP, sufficient progress in biometric technology could occur to make it a viable option for implementing say a national crime information system, or even an election system.

 

B.  CADD – COMPUTER-AIDED DRAFTING AND DESIGN

 

Definition

 

CADD refers to the use of a computer graphics system to create, modify, manipulate, and display drawings and diagrams. CADD assists engineers, architects, and designers in the same way word processors assist secretaries and the general population. Drawings, designs and diagrams stored as CADD files are more easily accessed and modified compared to paper blueprints. When used for mapping, CADD systems treat map sheets or drawings as separate entities with little or no continuity across map sheets.  While some CADD systems may contain limited database management capabilities, they seldom have map registration or map projection transformation capabilities.

 

 

 

Applications

 

CADD has promising applications in the following areas of government:

 

§         Public Works and Utilities (DPWH)

§         Urban Planning and Zoning  (LGUs)

§         Storage and Retrieval of Architectural Plans  (LGUs)

§         Industrial and Product Designs  (Design Center)

§         Storage and Retrieval of Engineering Plans and Drawings (IPO)

 

Considerations

 

The use of CADD technology for the storage and retrieval of plans, drawings, and designs will entail modernization of the equipment and staff skills of the agencies or local government units to be affected. This will require capital expenditure without any immediate tangible benefits, as it will take a while before a sufficient inventory of drawings in electronic form becomes available.

 

Prognosis

 

The technology is proven and mature, but the lack of immediate tangible benefits does not make this a high priority for government. Nonetheless, it may be considered an investment for the future. 

 

 

C.           DATA WAREHOUSING / DATA MINING / DECISION SUPPORT SYSTEMS / EXECUTIVE INFORMATION SYSTEMS

 

Description

 

These technologies collectively provide automated tools for data analysis in support of decision making.   They include technologies and IT facilities to store and gather data from individual transaction databases into massive databases and systems to extract, analyze and present data into forms that are meaningful to decision makers.

 

Data warehouses are large data repositories purposely designed and organized to allow analytical processing directly performed by users.  They allow more "data-based" decision making through the use of analytical models based on historical data. The use of data warehousing as decision support systems or executive information systems, has been receiving a lot of attention because it avoids the need to unite all systems into one processing system in order to get a consolidated enterprise-wide picture. Instead, the data warehousing concept precisely is built on the collection of data from multiple processing systems, organized through metadata which include data summaries that are easier to index and search.

 

Data mining goes beyond changing or enhancing data presentation for decision making.   Its main purpose is to discover previously unknown relationships among data items such as  possible cause-and-effect relationships.  It uses automated tools to look for hidden patterns among data sets.  Statistical techniques have long been developed precisely to look for correlations and dependencies from datasets.  Conceptually, however, data mining technology is different in that it is designed to have access to massive electronic databases and data warehouses.  Several data mining applications are now commercially available.  However, this field can still considered a complicated, diverse technology in its infancy.

 

The value of these data warehouses is greatly enhanced by integrating them with the Internet so they can be easily accessed from any location, at any time. This way, government workers out in the field or assigned to regional offices can use their browsers to access the data warehouse through their agency’s intranet.

 

Applications

 

Generically, data warehouses have been used in the automated prediction of trends and behaviors, and the automated discovery of previously unknown patterns. Given this, data warehousing and EIS/DSS can be employed in the following areas in government:

 

§         Economic modeling and analysis

§         Financial / Fiscal modeling and analysis

§         Agricultural sector modeling and analysis

§         Domestic and International Trade modeling and analysis

§         Employment data analysis

 

and practically any area of governance where analysis of massive historical data is applicable.

 

Considerations

 

Among the major considerations in the applicability of this technology are the following:

 

§         Cost. Data Warehouses require huge data storage – at least in the hundreds of gigabytes, and over time, in terabytes. The hardware resources needed to store and process this amount of data can be considerable. For example, a 1.2 terabyte disk storage system costs almost $ 1 Million each.

 

§         Sharing of data. Data warehouses will require collection of related data from different sources within government. It will certainly put to test the ability and willingness of agencies to share data with each other.

 

§         Long-term implementation. Because of the need for sufficient data to have accumulated before a data warehouse becomes useful, there will necessarily be a long “gestation” period – counted in years - before any benefits can be derived. If the project is to become successful, there must be a firm commitment to see the data warehouse project through its lengthy implementation.

 

§         Choice of subject/topic. Because of these three considerations, there is a need to choose the subject or topic of the data warehouse to be implemented very carefully. It must be focused on a critical function of government to make it worth the investment cost and long-term effort.

 

Prognosis

 

The cost and high chances of failure may indicate that data warehousing should be given a relatively low priority. However, the clear lack of information-based decision making in government suggests that, at the very least, one or two pilot warehouses addressing key areas should be set up. Government cannot afford to keep postponing this, as the long implementation requirement means that it will take five to ten years before any benefits accrue.

 

D. DISTRIBUTED DATABASES

 

Description

 

Relational database technology now makes it possible to build applications where the database tables may physically reside in different hardware. Stored procedures and ODBC allow programs running on one machine to access a database that resides in another machine. Two-phase commit mechanisms with automatic transaction rollback provide support for online mirroring of databases, i.e. simultaneously maintaining two identical copies of the database while ensuring integrity. Most database management systems also support database updates from transaction logs, a feature that can be used to automate offline mirroring of databases.

 

Applications

 

Distributed databases allow greater flexibility in designing and building integrated applications that cross geographical and bureaucratic boundaries. For example, access to remote databases via ODBC and/or stored procedures can be employed to allow consolidation of information that comes from servers of different agencies. Similarly, mirroring techniques can be employed to support centralized repositories of consolidated data from the field, even as local subsets of the data exist on field computers to support distributed transaction processing.

 

Considerations

 

Practically all the major commercially available database management systems support distributed processing techniques. And systems have actually been built and operated successfully employing this technology. Building distributed database applications in government would entail:

 

§         More powerful, and therefore more expensive, database management system software;

§         Special expertise to design the database, and build more sophisticated applications;

§         Planning and coordination to ensure the availability and integrity of the data;  and

§         Increased networking among government offices to allow sharing of databases.

 

Prognosis

 

Given the devolved, decentralized nature of operations government, distributed database technology is a must in building efficient integrated information systems. The only major obstacles are the higher cost (due to more expensive software and increased networking) and limited manpower (for the expertise in planning, building and in coordination). These can be solved with careful resource allocation and private sector involvement.

 

 

E.   ELECTRONIC COMMERCE

 

Description 

 

Electronic Commerce is the use of computers and telecommunications networks to facilitate business transactions like the buying and selling of products, services, and information. E-commerce can be generally classified into two types: business-to-consumer and business-to-business. While e-commerce has existed since the early 1970's through technologies like EDI and data encryption, it caught wide public attention only recently as several e-commerce sites sprung up in the Web.  E-commerce over the Internet allows the promotion, buying, and selling of goods and information that cut through geographical and/or political boundaries. Perhaps the best example of successful e-commerce over the Internet is the popular Amazon.com, which allows users to search for and order books, gifts, CDs, and videos online.

 

Applications

 

E-commerce technology can improve governance through its application in at least the following areas:

 

§         Government procurement/divestment. The whole process of procurement -- from pre-qualification of suppliers, to consolidation of requests from agencies, to bidding and monitoring of status and delivery -- lends itself well to the application of e-commerce. Similarly, auctions and bids such as those for privatization of government assets and confiscated smuggled goods have a lot of successful precedents on the Web.

 

§         Government Securities Auction and Trading. The Philippine Bureau of Treasury has pioneered in the use of e-commerce in the Philippines through its electronic auction and electronic trading facilities for government securities. These facilities employ the proprietary networks of Bridge and Reuters. The BTr recently introduced an Internet-based facility for the public to buy Treasury Bills through its Small Investor Program agents. Together with the DOF it is looking into the establishment of an Internet-based bond exchange.

 

§         Document/form submission. One way to improve the efficiency of government transactions with the public is through electronic submission of required forms and documents. A pilot project at the Bureau of Customs showed how processes can be improved and the delays minimized through the electronic submission of import declarations. With the growing number of Philippine companies connected to the Internet, there are many government services that can benefit from the application of this technology. 

 

Considerations

 

Growth of e-commerce in the Philippines would depend on two things:

 

§         Security and authentication. Because e-commerce involves transfer of money, goods and/or services, security of transactions and authentication of transacting parties are essential. One way of achieving this in a "closed system" (i.e. where there is a limited, identified set of participants) is to set up a Virtual Private Network with encryption among the transacting parties. This approach may be resorted to in doing e-commerce with, for example, registered brokers/dealers, top taxpayers, and banks. It will not apply, however, to an "open system" where the general public is involved. It would be prudent for government to limit its e-commerce applications to closed systems in the meantime.

§         Lack of legal infrastructure. To protect transacting parties, and ensure compliance with rules and collection of appropriate taxes, the existing legal infrastructure would have to be revised. In the US, for example, there are laws (e.g. the Mail/Telephone Order Rule, and the Fair Credit Billing Act) which effectively safeguard the rights of transacting parties in e-commerce. Similar laws and the appropriate mechanisms for implementing them would have to be introduced here.

 

Prognosis

 

Security and authentication problems and lack of legal infrastructure make it difficult to pursue e-commerce for the general public. However, there are local precedents for the successful implementations of limited e-commerce (e.g. closed system) such as the auction and trading of government securities, where the parties involved may come up with their own contracts and operating covenants to ensure the enforceability and legality of their transactions. Given these, the government should look into more of these opportunities, not only for improving efficiency in at least some aspects of its operations, but as a way of "testing the waters" for more ambitious e-commerce applications in the future when the security and legal issues shall have been resolved.

 

 

F.  ELECTRONIC DOCUMENT MANAGEMENT

 

Description

 

With the spectacular growth of the web and other IT trends, re-purposing of already published materials will be a sunshine industry. “Re-purposing" is a catch-all term for conversion of a broad range of different publishing types and components:

 

§         Printed Documents. Electronic documents make up the smallest fraction of the total mass of published materials today. Converting these into electronic files will take either of two forms:

 

Ø      Scanning to a bitmap image for indexing, or

Ø      Capturing the content via optical character readers (OCR) and converting it into a format that can be selected using cut-and-paste or cut-and-copy features available in most software applications.

 

§         Digital Documents. Files that are already in electronic form can be converted to other formats in a number of ways. Many are already being taken apart and recomposed in Hypertext Markup Language (HTML) for uploading to the Web. Many others are being converted to PDF (Adobe) format because it retains the integrity of the source document much better, with all elements including fonts, typography, layout, and vector graphics intact.

 

§         Photos and other Bitmap Graphics. Bitmap graphics that are large in storage size and saved in a broad range of file types are being compressed and converted to more universal formats - .tif, .gif, and .jpg - primarily for accessing in HTML documents. PDF conversion of documents incorporating bitmap images offers very dramatic compression ratios of 50:1 (or even considerably smaller).

 

§         Vector Graphics. Maps, logos, and fonts are normally vector graphics that are small in size and perfectly scalable for viewing and printing. Since HTML cannot handle vector graphics, they need to be converted to bitmaps before conversion to .gif or .jpg formats.  Documents in such format as PDF are also available for viewing on the Web and with vector graphics compressed to about 4:1 ratio.

 

Two standards have emerged for cross-platform document file formats: HTML and PDF:

 

§         HTML. Documents marked up in the simple page description HTML can display in a variety of computer environments such as Unix, DOS, Windows, NT, and Macintosh. Yet balanced against the broad compatibility of this format are two factors: 1) the cost -- in time and money -- of converting documents from other document formats into HTML; and 2) the author’s lack of fine control over character fonts and page layout.

 

A new software category, called portable document applications, attempts to provide the best balance of all factors. It combines the compatibility of HTML with the page layout quality of desktop publishing applications, font quality of the Postscript language, compact file size of compressed image formats, and a simple interface designed for typical, non-programmer computer operators. The leading application in this category is the Acrobat suite of tools from Adobe Systems Inc.

 

§         PDF. Short for Portable Document Format, a file format developed by Adobe Systems. PDF captures formatting information from a variety of desktop publishing applications, making it possible to send formatted documents and have them appear on the recipient's monitor or printer as they appear on paper.   To view a file in PDF format, the Adobe Acrobat Reader is needed.  It is a free application distributed by Adobe Systems.

 

There are two Acrobat components to consider: the proprietary PDF file format and the suite of software tools (for browsing and editing to manipulate documents) stored in this file format. The two are used interchangeably but in fact they are distinct; PDF is the name of the file format and Acrobat is the suite of software tools. The Acrobat PDF file format is based on the Postscript language, also developed by Adobe. Like Postscript, Acrobat is vector rather than bitmap based. Vector file formats describe fonts, images and other page elements as a series of mathematical descriptions and relations. Character fonts are encoded as mathematical descriptions of lines, shapes and distances between sets of points. As an oversimplified example, the character “V” is fundamentally three points: the top left, top right, and bottom middle where the two lines intersect.

 

Applications

 

Government can find use for this technology in two ways. First, a central repository of official documents in electronic form can be set up to store and provide access to all future government public documents. Since practically all government offices already use PCs to generate their memos, orders, rulings and other documents, a central document repository can be achieved prospectively. All that is needed would be to set up a large server, perhaps at the National Archives, to where all government agencies would be required to submit electronic copies of all their official documents.

 

Second, the government should consider converting all existing documents into electronic form to save on storage space, make them easily accessible, and preserve their integrity. This is a much more complex and costly exercise because of the volume of documents for conversion.

 

Considerations

 

Creating, storing, and disseminating documents in digital form offer substantial advantages over traditional print publishing for a variety of reasons:

 

§         Capability to communicate beyond the printed word. Digital publishing allows addition of motion, sound, forms, interactivity and linking to a document.

 

§         Distribution Costs.  Printing documents first from a central source then distributing them on paper requires careful anticipation of demand with costly consequences.  Distributing documents electronically offers the recipient the option to print it as needed and secures access to documents with passwords and digital signatures. A CD-ROM, for example, can hold text for up to the equivalent of 1700 lbs. of paper. If the cost of printing, postage, of storage and preservation are added, the savings would be immense.

 

§         Search and Retrieval. Paper files can only be filed by one index field. Access requires training, and re-filing is prone to errors. Statistics show that 7.5% of paper documents get lost completely. In contrast, digital documents can have any number of keywords attached and access is controllable through password protection. Hyperlinking between documents speeds up access to related information. If sufficient processing power is available, “brute force” searching through voluminous text is also possible.

 

      On the other hand, there are negative factors to consider such as:

 

§         Cost. Prospectively, the cost is minimal, mainly covering central document repository and end-user license for the software tools (HTML or Internet browsers and the Adobe Acrobat Reader for viewing PDFs are free and downloadable from the World Wide Web).  This pales against the potential cost savings from reduced demand for paper documents, document transport, and handling charges. However, converting old documents to electronic would be quite expensive, and government may very well limit its scope.

 

§         Security and "Turf". Some agencies treat their data and information as proprietary secrets and do not look favorably on sharing of information. This mindset will have to be changed to one of transparency and service-orientation.

 

Prognosis

 

Converting the same document into other information products from essentially the same source material means less publishing and document-related cost.  From a cost/benefit standpoint, re-purposing or electronically converting and disseminating existing documents means that agencies can reuse existing information resources to accomplish newly defined communication objectives. New distribution channels can be exploited.  Budgets can be spread over a broad range of applications. For instance, the production costs of promotional CD-ROMs can be amortized to include the cost of and uploading the same materials to the Internet and producing brochures and internal IEC (information, education, and communication) materials.

 

 

G.  GEOGRAPHIC INFORMATION SYSTEM (GIS)

 

Description 

 

A Geographical Information System (GIS) Is an information technology application for the conversion, integration, management manipulation and analysis, query, deployment, and use of geographically referenced information.  What differentiates a GIS from an MIS application is the use of maps with related attributes describing features on the map.  It is a very powerful visualization and analysis tool that helps uncover spatial relationships not possible in the traditional sorts and other manipulation of databases (i.e. attributes of map features). In the new paradigm.  GIS is really part of the MIS of an organization, which handles all sorts of information, including spatial information.

The other spatial technologies provides information inputs (content) to the GIS.  In addtion, transaction based information gathering can be integrated to the GIS provided each record is geographically referenced.

 

The strength of the GIS for government information systems is its geographic integration capability.  Thorough GIS, it is possible to immediately link and visualize most government databases, that could not be linked before, through geography or location.

 

Applications

 

National and local governments worldwide, including a few in the Philippines, have utilized GIS technology for productive uses in the following applications.

 

·        BaseMapping and Thematic Mapping

·        Integrated Land Information Systems

·        Environment Monitoring and Resource Management

·        Precision Agriculture

·        Population and other Censuses

·        Elections Management and Monitoring/Reporting

·        Epidemiological/Health Studies

·        Facilities Management

·        Infrastructure Planning, Construction Management and Monitoring

·        Disaster Preparedness Planning and Damage Assessment

·        Public Safety/Public Order/Defense Applications

·        Transportation and Traffic Management

·        Land Use Planning and Zoning Administration

·        Tourism Planning and Tourism Services Information Systems

·        Promotion of Economic Development

·        Environmental Impact Analysis

·        Real Property Estate Valuation. Tax Assessment, and Marketing

·        Teaching Geography and other applications

 

Consideration

 

·        Infrastructure – Most systems run on PCs and/or Unix Servers.  System peripherals like digitizers, plotters, scanners, printers are widely available.  There are many commercially available software (GIS, Image Processing, Digital Photogrammetry and cartography, the price ranges from free to desktop systems to the expensive high end professional systems.  The Philippines is the only country among the original ASEAM without ground receiving station fro remote sensing data, thus it currently depends on acquisition services of remote sensing data service providers.

 

·        Data – Local implementation of GIS is hampered by the lack of or poor quality of digital basemaps or cartographic database. The development of this database is a priority element in the full development of GIS applications in the country. Data standards are not in place. This is necessary for the sharing of geographic information among agencies and the local government units. Many agencies of government have started to build their digital spatial databases that have turned out to be of poor quality. There must be a policy on investments in the build up of digital databases to ensure that these investments do not go to waste.

 

·        Data Sources – The national government is the largest producer, collector of geographic information. To date much of these information are on paper. They are spread out in the bureaucracy and some of these data sets have in fact been digitized more than once by several groups. It is necessary to pinpoint to owner of the data who will be responsible for their conversion to digital forms. Data is the most expensive component of GIS and its integrated development must be planned well.

 

·        Orthophotos and OrthoImageries – More modern implementations of GIS now use orthophotos and orthoimages. The advantage of using orthophotos/orthoimages is that the utilization of GIS is decentralized and really put in the hands of users. Feature extraction, for instance, can be now in the hands of, say, the land use planner, the forester, the assessor, the road planner, etc. instead of the GIS specialist or GIS data analyst.  Orthophotos and orthoimages are geographically rectified photos and imageries with known accuracies throughout the orthophoto/imagery dataset.

 

·        Implementation – The process of setting up a GIS requires careful planning and implementation, including:

 

Ø      Identification of users and their functional and information requirements
