SigmaSAR (Beta version 2.0.) is the follow-on of version 1.0. developed at Microwave Remote Sensing and Data Processing Division, MRSDPD/MRS&GDPG/DPPA&WAA/NRSC to generate Sigma Naught Backscatter Images for Level-1 Ground Range, Level-1 Slant Range and Level-2 and Level-2A GeoTIFF data products of FRS-1 ,FRS-2, MRS and CRS operational modes of RISAT-1. The software has been updated to generate Sigma Naught Backscatter Images for Level-2A Georeferenced GeoTIFF data products of FRS-1, MRS and CRS acquisitions of RISAT-1. RISAT-1 Level-2 Terrain corrected Geo-Referenced Product named as "Level-2A Enhanced Terrain corrected Geo-Referenced Product" is an improved version which was released to the user community in 2016. Though Level-2 and Level-2A are geometrically at par in planar regions, Level-2A product has significant improvement of geo location accuracy in hilly regions .The product includes Layover Mask and Local Incidence angle along with the files already defined for the Level-2 product. This product uses the True height values even in highly undulating terrains. Download SigmaSAR (Beta version 2.0.) RISAT-1 Data Products Format (Version 1.4) may be referred for further details. SigmaSAR (Beta Version 2.0.) can generate Sigma Naught Backscatter Images for L2A products taking into consideration the Local Incidence Angle Map with improved accuracy in normal terrain and more so in hilly terrain.

NCC Generation Utility for IRS Data Remote sensing satellites view the earth in different spectral bands, viz. near infrared (NIR), red, green, and blue bands. In the absence of a blue channel from IRS-1C/1D onwards, interpreter creates color images using near infrared, red, and green bands in what is known as a false color composite(FCC). FCC does not look like natural representation of earth system as we view the earth ith the naked eye. e.g. Green vegetated areas appear Red in FCC whereas on real world we see it as green. For a trained interpreter, this does not pose any problem. However, for the non-remote sensing professional, this becomes a handicap. To overcome this, there is a requirement to generate natural color composites (NCC) from the given false color composite. This needs the simulation of blue band and create NCC by combining it with green and red bands. The NCC S/W module has been developed using the coefficients derived using spectral transformation method to establish a relationship between false color and true color image pairs provided by a sensor with all the four bands. These coefficients seem to work on a large number of images of different seasons, provided similar spectral bands and terrain are used. With the demand from the users for the Natural Color Conversion software, the software utility is developed at NRSC for users to create NCC at their end by using different sensors data sets from IRS-Resourcesat-1 and Resourcesat-2 Multispectral data.

MUlti DATe Registration [MUDAT] is a software package developed at AIPD/DPSG/SIPA, Space Applications Centre, Indian Space Research Organiation for registration of RISAT-1 multidate data. Download User Manual..The utility performs registration of RISAT-1 Level-2 Georeferenced multidate products to the reference product and hence generates other dates registered products by resampling. The registered products are generated in the same format [CEOS / GeoTIFF] as the original product.Download MUDAT..
