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

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. Objective of the study

Minutes of the meeting (17 July 2013) and progress Comments and suggestionProgress Web processing services are now available for real time data updation, assigning weight to data sets etc. Completed Tool should be upgraded towards providing high level user - oriented services for suggesting alternative scenarios for the above applications. Under development The project is making use of freely available and open source software tools for WPS. Additional features have been added to the available tools to support site selection and structure suggestion Using available and open source s/w and tools (QGIS, Geoserver, PostGIS, Geoexplorer, Apache, Apache Jmeter etc. The tools and services should be shared with GISE Lab IIT Bombay for further evaluation and suggestion / comments. Completed and received suggestions for the project Performance and evaluation of technologiesUsed three server technologies for performance Further developmentUnder progress

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