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)

ARSF internal processing

  • Common or known problems (in ARSF-DAN processing)
  • Running old glibc with azgcorr.491? (obsolete)

  • LIDAR processing details
  • ALS Post processing

Navigation/GPS data handling
