A number of bug fixes to ILWIS 3.7. 3.7.2 24 May 2011 A number of bug (from 3.7.1) fixes. 3.8 3.8 April 7, 2012 Massive rewrite of the whole visualization of maps. This rewrite expanded the tools for visual analysis substantially and improved the overall performance of the drawing process. 3.8.1 September 19, 2012 A number of bug fixes. 3.8.2
Remote sensing systems gather data via instruments typically carried on satellites in orbit around the Earth. The remote sensing scanner detects the energy that radiates from the object or area of interest. This energy is recorded as an analog electrical signal and converted into a digital value though an A-to-D conversion.

Remote sensing applications are similar to graphics software, but they enable generating geographic information from satellite and airborne sensor data. Remote sensing applications read specialized file formats that contain sensor image data, georeferencing information, and sensor metadata .
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a Japanese remote sensing instrument onboard the Terra satellite launched by NASA in 1999. It has been collecting data since February 2000. ASTER image of Rub' al Khali (Arabia's Empty Quarter)
IKONOS originated under the Lockheed Corporation as the Commercial Remote Sensing System (CRSS) satellite. In April 1994 Lockheed was granted one of the first licenses from the U.S. Department of Commerce for commercial satellite high-resolution imagery. [ 6 ]
The software is released under a free licence; a number of contributors outside CNES are taking part in development and integrating into other projects. [ 3 ] The library was originally targeted at high resolution images acquired by the Orfeo constellation : Pléiades and Cosmo-Skymed , but it also handles other sensors.
A bistatic remote sensing system would separate source 3a from sensor 3b; a multistatic system could have multiple pairs of coupled sources and sensors, or an uneven ratio of sources and sensors as long as all are correlated. It is well known that bistatic and multistatic radar are a potential means of defeating low-radar-observability aircraft.
