These data are often obtained simultaneously in and mode with significant share of Spectral Bands covering Infrared Optical Spectrum. Some satellites acquire the data in a regular, usually a few week period. Other more modern satellites are able to take a data according to the customer’s request. In both cases extensive data archives are available containing all the images acquired since the launch of the satellite. The data are suitable for mapping or updating of maps in the scale range 1:100,000 – 1:25,000. Amity Institute of Geoinformatics and Remote Sensing (AIGIRS) The major application includes:              Regional planning Urban development monitoring Land cover/Land use mapping and change assessment Vegetation monitoring Mapping of agricultural areas Classification of agricultural crops Mapping of forest areas Classification of forest ecosystem Water Logging monitoring Geological mapping Geomorphologic mapping Disasters impacts mapping DEM generation Amity Institute of Geoinformatics and Remote Sensing (AIGIRS) Satellite data with V e r y H i g h R e s o l u t i o n are defined at about 1 m. by a These data could obtained only in mode, more often in combination of Panchromatic and Multispectral mode.
