A satellite-only algorithm (which does not need ancillary data on soil surface roughness and vegetation) to retrieve soil moisture is tested over ambhas site (www.ambhas.com) in India. The satellite data used is L-band ALOS PALSAR which has all weather capability. The estimated soil moisture had a spatial resolution of 25 m capable of estimating crop […]
MAPSM algorithm has been applied in the state of Karnataka to retrieve the higher resolution soil moisture. SMOS has been used for the passive microwave data and RISAT-1 has been used for the active microwave data. The high resolution soil moisture product can be used for several purposes e.g. identification of drought-impacted farmers and irrigation […]
Groundwater is an important source of the fresh water for drinking and irrigation purposes. For the suistainable management of groundwater resources, scientific assessment is essential. Remote sensing provides a way to quickly assess the groundwater resources for the large region, which is cumbersome and costly with manual measurements. Remote sensing based GIS layers can be […]
