In-house developed scripts

This is a list of some of the scripts that have been developed at ARSF-DAN to aid in processing and handling of the data. As these may be useful for further processing of ARSF data descriptions are included here. If you have an interest in using one of these scripts, or would like to know if one would be useful for what you are trying to do, then please contact us and we can supply them to you with limited help.

We also have some general purpose scripts on ​GitHib

Please note that these are specifically designed for processing using linux systems as set up at ARSF-DAN. There are no guarantees that they will work with other system set ups. Some scripts are simply just wrappers for using other free packages (such as liblas or LAStools). A lot of these scripts are only suitable for working on raw data and not the standard delivered level-1 data

LiDAR
