Based on the initiation taken by SWa. RMA, GIS trainings were imparted in phased manner. GIS TRAINING These River basins and its sub basin boundaries Were fine-tuned now in GIS techniques, utilizing the services of above 20 GIS trained Officers. 37 officers belong to SWa. RMA, 1: 50, 000 Topographic maps of SOI, IWS, SG&SWRDC, EIC office, SRTM–DEM elevation DRCS and WRD Regions were data of USGS were trained in ARC GIS software. utilized for fine tuning the boundaries.
