Figure 1: Distribution of the Questionnaires sent back 
51 Organisations Using Laser Data 
It seems like laser scanning is so far mainly used within the mapping communities (see Figure 2). This can also be due 
to the fact that the questionnaires were mainly sent out within this area. There are many consultant agencies who hope 
for other applications, e.g., telecommunication and power industries, but so far these are minor applications. But the 
different applications show the high potential of the new technology which is probably not yet coming up against 
limiting factors. The main application areas of laser data are the production of DEM or DSM and the main reasons for 
using laser data are point density, high precision and cost effectiveness (see Figure 3). Users also mention short 
production times as very important.
