- [ CASI]

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

LiDAR processing
- Remove noisy points from delivery files COMING SOON

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

Other useful information

Choosing an appropriate Eagle/Hawk map pixel size
Creating a DEM for hyperspectral processing
ATM and CASI
- Converting ATM band 11 to (brightness) temperature
- Finding out what the wavelengths and bandwidth are (for a specific flight)

In-house produced scripts and software which may be useful for end users (COMING SOON - for now see here)

Links to external software that may be useful
- FWTools - includes the GDAL tools for data conversion and the free OpenEV viewer (vectors + rasters)
- GRASS - freeware GIS (powerful and full featured, but hard to use)
- fugroviewer LiDAR viewer (requires registration)
- LAS tools for manipulating LiDAR files.
- ExifTool for reading tags in RCD tiff images.
- fityk curve fitting tool (useful for full waveform LiDAR data). Free for version 0.9.8 and older.
- GDAL Library useful for data format conversions amongst other tools. For experienced users.
- PROJ4 cartographic projections library useful for re-projecting point data but can be difficult to use.
