Welcome to the ARSF Data Analysis Node help desk. We are here to help you with any queries you have regarding the processing of your ARSF 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 [wiki:AboutUs#ContactUs contact us].

== Information about data processing prior to delivery ==

For information on what happens to the data prior to delivery please check these pages:

 * [wiki:Procedures/hyperspecprocessing Hyperspectral data processing procedure]
 * [wiki:ProcessingAtDAN/Lidar LiDAR data processing procedure] 
 * [wiki:ProcessingAtDAN/RCD RCD data processing procedure] 

For information on '''sensors''' and their specifications please see the [wiki:SensorsDev 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
  * [wiki:Processing/aplquickstart Getting started guide] to using APL for Eagle / Hawk processing.
  * [wiki:Processing/AplUserGuide APL processing level 1 to level 3 guide]

 * LiDAR processing
  * [wiki:Processing/LidarNoisyPoints 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. 

 * [wiki:Downloads/Tutorials Tutorials]


== Frequently Asked Questions ==

We host a page of [wiki:FAQ 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.

== Reports ==

Reports written by ARSF-DAN on various instrumentation and processing issues can be found [wiki:Reports here].
