Abstract:

Several surface water bodies exist in Anantapur district, Andhra Pradesh and A robust methodology has been developed for extraction of water spread areas of the district, based on the processing of satellite images with open-source data and software solutions. Anantapur district lies between 13040' and 15015' northern latitude and 76050' and 78030' eastern longitude. It is bounded by Bellary, Kurnool district on the north, Cuddapah district of Andhra Pradesh and Kolar district of Karnataka on South East and North respectively. QGIS functions as geographic information system (GIS) software, allowing users to analyze and edit spatial information, in addition to composing and exporting graphical maps. QGIS supports both raster and vector layers; vector data is stored as either point, line or polygon features. Multiple formats of raster images are supported, and the software can georeference images. The classification of extracted surface water bodies from 2006 to 2015 carried out and evaluated. The regression mean square (R2) value is 0.3885 for the trend analysis of number of water bodies, and the maximum and minimum number of water bodies was observed during 2014 and 2007 respectively. The R2 value is 0.482 for the trend analysis of surface water bodies and maximum and minimum area of water bodies was observed for the years 2014 and 2006 respectively.
