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.
Hence the remote sensing data has to be classified first, followed by processing by various data enhancement techniques so as to help the user to understand the features that are present in the image. Such classification is a complex task which involves rigorous validation of the training samples depending on the classification algorithm used.

Quantitative remote sensing is a branch of remote sensing. The quantitative remote sensing system does not directly measure land surface parameters of interest. Instead, the signature remote sensors receive is electromagnetic radiation reflected, scattered, and emitted from both the surface and the atmosphere . [ 1 ]
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.
Spectroradiometry is a technique in Earth and planetary remote sensing, which makes use of light behaviour, specifically how light energy is reflected, emitted, and scattered by substances, to explore their properties in the electromagnetic (light) spectrum and identify or differentiate between them.

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 .
