Remote sensing of earth has come a long way from nineteenth century aerial photography to latest UAV remote sensing. In general sense, remote sensing at present means satellite remote sensing and it started with the launch of Landsat-1 in 1972 for civilian applications. In 1979, Seasat-1 became the first RADAR imaging satellite and started a new domain of remote sensing. Over the following years, the field of satellite remote sensing has seen many exciting new developments such as new higher spatial resolution optical and radar systems, hyperspectral sensors, important by-products such as digital elevation model (DEM), furthermore development of new processing techniques using machine learning. At present, Satellite series like Sentinel and Planet Labs are revolutionizing the sector by providing high spatial, spectral and temporal resolution data either free or at very low cost.

The integration of different types of remote sensing data, along with ancillary data from different sources, is driving many new scientific investigations ranging from estimating forest biomass to mapping of Mars surface for finding minerals. Remote sensing data is also helping to develop a better geographical information system (GIS) which in turn can be used for education, land management, natural resources management, environmental and aeronautical applications. This workshop will update the knowledge of these topics.
