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.
