From the laser data it will be possible to create a surface model (DOM / DSM). This surface model will define the surface that will consist of the highest points. The model will therefore include terrain, vegetation and other building sites. By including all rising objects, one will have a good basis for performing calculations of signal strength for e.g. radio signals or noise with good accuracy.
If surface models exist for the same area from different times, a change analysis will reveal where changes have occurred due to man-made or natural changes.
