= ARSF Help Desk = 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: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] * [ LiDAR data] COMING SOON * [ RCD data] COMING SOON For information on sensor specifications please see the relevant sensor pages: * [wiki:Sensors/Eagle Eagle] * [wiki:Sensors/Hawk Hawk] * [wiki:Sensors/LeicaLIDAR Leica ALS50-II LiDAR] * [ Leica RCD105 Camera] * [wiki:Sensors/Fodis FODIS] * 'Retired' instruments * [wiki:Sensors/ATM ATM] * [wiki:Sensors/CASI 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 * [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 * 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. * [wiki:Downloads/Tutorials Tutorials] == Other useful information == * [wiki:Processing/PixelSize Choosing an appropriate Eagle/Hawk map pixel size] * [wiki:Help/DEM_scripts Creating a DEM for hyperspectral processing] * ATM and CASI * [wiki:Processing/BrightnessTemperature Converting ATM band 11 to (brightness) temperature] * [wiki:Processing/Wavelengths Finding out what the wavelengths and bandwidth are] (for a specific flight) * [wiki:InHouseScripts In-house produced scripts and software which may be useful for end users] (COMING SOON - for now see [wiki:scriptlist here]) * Links to external software that may be useful * [http://fwtools.maptools.org/ FWTools] - includes the GDAL tools for data conversion and the free OpenEV viewer (vectors + rasters) * [http://grass.fbk.eu/ GRASS] - freeware GIS (powerful and full featured, but hard to use) * [http://www.fugroviewer.com/ fugroviewer LiDAR viewer] (requires registration) * [http://www.cs.unc.edu/~isenburg/lastools/ LAS tools] for manipulating LiDAR files. * [http://www.sno.phy.queensu.ca/~phil/exiftool/ ExifTool] for reading tags in RCD tiff images. * [http://fityk.nieto.pl/ fityk] curve fitting tool (useful for full waveform LiDAR data).
