WPS Application Development of geospatial web application for site selection

1. WPS Application Development of geospatial web application for site selection for artificial recharge of groundwater Principal Investigator: Ritesh Vijay Co-Investigators: Asheesh Sharma CSIR-National Environmental Engineering Research Institute Nehru Marg, Nagpur 440 020 October 10, 2013

2. Objective of the study • To develop a geospatial web application for site selection for artificial recharge of groundwater. • To demonstrate the application considering local climatic, topographic, hydrogeologic and land use conditions.

3. Minutes of the meeting (17 July 2013) and progress

4. Modified approach PostgreSQL +PostGIS Geoserver (open source Java libraries) Soil, Geology, Geomorphology, Land use, Contour/DEM, Water table etc. Feature Data GML WMS (maps) KML WFS (Features) WPS (Processing) GML GML WFS – web feature service WCS – web coverage service WPS – web processing service WMS – web map service GML– geography markup language KML – keyhole markup language Feature viewer or editor Analytical tool (GIS-AR) KML viewer Map viewer Java/Servlet Client Web browser Apache Tomcat
