| Abstract | Existence of geographic information archives dates back to the very origin of human civilization. Archaeological excavations have unearthed earliest attempts at storing and reusing of geographic information pertaining to territories inhabited by primitive settlers on mediums ranging from earthenware and animal skins to cave walls. The science of cartography or mapping that played a decisive role in spreading civilization and human knowledge over the earth formed the primary source of information for early geographic information archives. While this trend continues to- date, those archives were continually enriched with topographically related information such as population, trade and natural resources. The modern geographic information archives that are stored in computerized databases contain a spectrum of data that is capable of providing valuable information to areas ranging from education, local government to trade and commerce. These databases that inherently carry a vast amount of data are controlled by geographic information systems (GIS) capable of analyzing and processing data in relation to maps that form a basis for such data. The GIS technology allows efficient and systematic storage and retrieval of geographic information. However, while the server- end of GIS technology continued to advance, issues pertaining to the client mechanisms for querying these databases and efficient retrieval and representation of geographic information were not adequately addressed. This research work investigates the features required for a geographic information browser that is capable of accessing GIS databases over the Internet to efficiently retrieve data and represent information in a format termed active documents. As part of the research work a specialized GIS database browser termed Geo- Browser capable of efficient query management for optimal use of network bandwidth was designed and implemented. Geo- browser use an innovative mechanism to display query results as dynamically linked information sources suitable for access in a network environment. The Geo-Browser support queries containing spatial relationship and attribute selection criteria and format queries to minimize GIS database response times. |
