ASTER can collect data in 14 spectral bands from the visible to the thermal infrared.
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a multispectral imager that was launched on board NASA's Terra spacecraft in December, 1999. This version contains both ground level samples and items above ground level (such as buildings, bridges, trees etc). It was generated from LIDAR data taken in the spring between 20. The AHN DEM is a 0.5m DEM covering the Netherlands.
Starting in 2009, the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) began the process of generating annual crop type digital maps.
