FAQ/apldemformat
v4 v5 4 4 APL expects the Digital Elevation Model (DEM) to be in a 1-band ENVI BIL or BSQ file format. This is a simple binary format where the data is stored as a string of binary information with an accompanying header file that describes the number of bands / lines / samples. Further information on this file format can be found in the ENVI tutorial: [http://www.exelisvis.com/portals/0/tutorials/envi/ENVI_Intro.pdf] 5 5 6 The elevation data should be projected in WGS84 Latitude and Longitude with heights referenced to the WGS84 spheroid. 6 The elevation data should be projected in WGS84 Latitude and Longitude with heights referenced to the WGS84 spheroid. If possible a Digital Surface Model (DSM), providing the top of canopy / building height is preferred. 7 7 8 8 For preparing a DEM for use in APL the ARSF DEM scripts (available to download from https://github.com/pmlrsg/arsf_dem_scripts) can be used. For more details on usage see [https://github.com/pmlrsg/arsf_dem_scripts/blob/master/doc/source/tutorial_lidar.rst the tutorial].
