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
  • Processing full waveform data
  • LiDAR Software

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.

• Tutorials

Frequently Asked Questions

We host a page of Frequently Asked Questions which we try to keep up to date. If you haven't been able to find a solution to your problem so far then this is a good place to check next.
