Data processing

End user data processing

• Creation of DEMs from LIDAR point clouds
• Creation of DEMs from NextMap data (subsetting and resampling)
• Creation of DEMs from SRTM 90m data
• Conversion of vector maps to raster maps and GeoTiff images
• Choosing an appropriate pixel size
• Finding out what the wavelengths and bandwidth are (for a specific flight)
• Handling FODIS/ILS data
• Converting ATM band 11 to (brightness) temperature

Useful tools

• ​FWTools - includes the GDAL tools for data conversion and the free OpenEV viewer (vectors + rasters)
• ​ENVI Freelook - image viewer part of ENVI, good for viewing images and taking spectral profiles
• ​GRASS - freeware GIS (powerful and full featured, but hard to use)
