NERC-ARF Help Desk

Welcome to the NERC-ARF Data Analysis Node help desk. We are here to help you with any queries you have regarding the processing of your NERC-ARF data. Please spend a few moments to check through these pages to find the answer to your query. If you cannot find the answers you are looking for then please contact us.

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.

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

• Hyperspectral processing
  • Getting started guide to using APL for hyperspectral processing.
  • APL processing level 1 to level 3 guide
  • Creating a mosaic from level 3 data
  • Basic information for using azgcorr to process level 1 to level 3 (for older data)

• LiDAR processing
  • ​Creating a DEM from LiDAR Using ARSF DEM scripts (​download scripts)
  • Remove noisy points from delivered LiDAR point cloud files
  • Processing full waveform data
  • Information on LiDAR intensity data

Tutorials

NERC-ARF-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.

Reports

Reports written by NERC-ARF-DAN on various instrumentation and processing issues can be found here.

Workshop

We hold an annual workshop for users of NERC-ARF data, this is normally held at PML in March with the option to join remotely. For more information about the next course or notes from previous courses please contact us.
