Information about data processing prior to delivery

For information on what happens to the data prior to delivery please check this page:

• Data processing procedures

For information on sensors and their specifications please see the sensors page.

Information about data processing after delivery

For information on using ARSF-DAN software or how to get the best from your data please check these pages. For information on using ARSF software please also see the tutorials section:

• Hyperspectral processing
  • Getting started guide to using APL for Eagle / Hawk processing.
  • APL processing level 1 to level 3 guide
  • Basic information for using azgcorr to process level 1 to level 3
• LiDAR processing
  • Remove noisy points from delivered LiDAR point cloud files

Tutorials

ARSF DAN are in the process of creating some tutorials, with downloadable data, to help users get to know the various software we provide. This is a good place to start if you have no experience with the processing software.
