Remote Sensing and Geographic Information Systems Driven Data Analysis

Remote sensingRemote sensing (RS) and Geographic Information Systems (GISGeographical information systems (GIS)) are routinely used in hydrologic data monitoring, mapping and modelling. This chapter introduces the basic concepts of the RS and GISGeographical information systems (GIS). The earth observationEarth observation (EO) satellites and missions, imageImage processing techniques, and spectral indicesSpectral indices are discussed. Similarly, the popular GISGeographical information systems (GIS) spatial and attribute dataAttribute data models are presented. Data sources for hydrology and water resources modelling are highlighted. Besides, a few prevalent commercial and open-source GIS and remote sensing softwareGIS and remote sensing software are enlisted. The chapter includes the RS and GISGeographical information systems (GIS) applications in flood management, droughtDrought monitoring, water quality monitoring and water body mappingWater body mapping.
