  • 摘要:GIS is becoming essential to understand what is happening and what will happen-in geographic space. Thisproject web based geographic information system (GIS) lets us visualize, question, analyze, and interpret datato understand relationships, patterns, and trends online. Most of the geo-portals which are web based primarilyprovide display of geo-data/ satellite images. But analysis of geographical data to solve the problem of realnature on the move is very limited. The proposed project work envisages development of a prototype forcarrying out multilayer GIS queries online using geo processing techniques and WPS. The development of thisprototype is aimed at providing support in decision making to the users online. Through this model, users canquery information of specific geographical area of interest from data spanning multiple layers. The queryresult will be retrieved by making use of geo-processing techniques, and Open Geo Consortium (OGC)compliant services such as Web Processing Service (WPS) and Web Map Service (WMS) etc. Spatial queriesare also performed on the resultant output obtained by spatial queries performed earlier, thus forming a chainof web of processing services
