Abstract
Geographic information system (GIS) has become an indispensable tool for analyzing and managing spatial data. The rapid growth of Internet provides highly customised, accessible and interactive sources of information and has created huge demand for application that uses geographic information system. The broad use of fast, up-to-date, reliable maps on the Internet will drive GIS industry to provide continually improving quality of information. Internet GIS technology provides dissemination, sharing, displaying and processing spatial information on the Internet. Internet based geographical data services mainly involve management of spatial and non-spatial data. Data pertaining to spatial attributes in a GIS can be efficiently managed with any relational database management system (RDBMS). When building GIS application for the Internet, a developer can choose any number of architectures, technologies and methods to deliver maximum information. The present paper describes the salient features of a spatial database that was developed by integrating thematic layers stored as feature classes in Interbase Object-Relational Database Model into a Java based Client/Server environment. The map data is handled by a group of Java Servlets in a Java Web Server and an Applet at the client end provides user interactivity. The system described in this paper aims to provide information on geology and mineral resources of North East India through a Web-based platform.
