ARSF-relevant

• ​Main ARSF home page This is the home page for the overall ARSF facility (not just the data processing part)
• ​NERC Earth Observation Data Centre The archive of ARSF data is publicly available here (after registration)
• ​NERC Field Spectroscopy Facility
• ​Natural Environment Research Council NERC is the funding body for ARSF
• ​ARSF Tools on GitHub A collection of tools for working with ARSF data (including reading LiDAR data in LAS 1.3 format)

LiDAR

Software

FW - Supports full waveform data.

• ​LAStools Toolbox for processing of LiDAR data (open source and commercial components, source available from ​GitHub)
• ​Laspy A Python library for working with LAS files
• ​OPALS Software for processing discrete and full waveform LiDAR data (commercial, academic licenses available). FW
• ​SPDLib Open source library for storing and processing discrete and full waveform LiDAR data. Supports reading/writing LAS and ASCII files. FW
• ​points2grid A tool for generating DEMs from LAS and ASCII files. Need to remove noisy points first.
• ​PulseWaves Tools for working with full waveform data, and library for reading full waveform data in the pulsewaves format. (open and closed source components). FW
• ​Fleurdelas An open-source IDL reader/writer for LAS files
• ​LibLAS C/C++ library for reading/writing LAS files (largely replaced with LASlib from LAStools and laspy)

Hyperspectral

Software

• ​APL Github page for our in-house hyperspectral processing code
• ​ATCOR Program for atmospheric correction of spectral remote sensing data
• ​TuiView (ARSF Fork) Open source geospatial image viewer, supports viewing spectral profiles and opening zipped bil files (as provided with ARSF deliveries). ARSF fork can also read level1b files. Original version available from ​here

Tutorials

Digital Photography

• ​ExifTool for reading tags in RCD tiff images.

General

Software

• ​ENVI Commercial geospatial image viewer.
• ​GDAL Geospatial Data Abstraction Library. An open source library for reading/writing common raster formats. Also provides a number of command line ​utilities for converting file formats, reprojecting data, creating mosaics etc.
• ​GRASS Open source GIS (powerful and full featured, but with a steep learning curve).
• ​QGIS Open source GIS package, latest version provides interface to GRASS tools.
• ​OSGeo4W Windows installation package for a number of open source remote sensing and GIS software packages (including GDAL, GRASS and QGIS).
• ​PROJ4 cartographic projections library useful for re-projecting point data but can be difficult to use.
