Web Based GIS Application using Open Source Software for Sharing Geospatial Data

Abstract

Web based GIS disseminate and shares geospatial data through internet for visualizing and decision making on area of interest (AOI) sitting across the globe. In order to make a cost effective implementation, operation and maintenance of geospatial data over the web, a cheaper yet feature rich alternative to commercial software is required which can be fulfilled by existing free and open source software (FOSS) for geographic information systems (FOSSGIS) and FOSS for web development. This paper provided an efficient approach to customize and integrate an application using FOSSGIS, FOSS web development software and database. It is observed that the presented application developed using FOSS technology enables user to plot the name and locations of interest, display and navigate the map and satellite image of AOI, perform spatial query, search the geographic location in the map, identify features, measure the distance between points and area of the object in the map in web environment.
