= Do the ARSF generate a DTM/DSM from LiDAR data? =

A common product for users to create from LiDAR data is a Digital Surface Model (DSM), which represents the elevation at the top of buildings / forest canopy and a Digital Terrain Model (DTM) which is the 'bare Earth' elevation (i.e., it doesn't include the height of buildings or vegetation).

We supply a LiDAR DSM patched with a courser resolution elevation model (normally ASTER) for use in APL for processing hyperspectral data. However, we don't provide a DTM. 

There are a number of software packages capable of creating DTMs and DSMs from the point cloud files we deliver (see our [wiki:Links links] page) and we recommend users spend some time looking at which package / algorithm produces the best results for their application. Although we are unable to provide help with specific software packages we can provide general advice on creating a DTM/DSM if needed.
