Abstract
Experiences from LiDAR Mapping in Finland

Airborne LiDAR has been used in Finland since 1998. The first projects were airborne corridor surveying mainly for road and railway design. Since that many communities ordered aerial LiDAR projects to get accurate models and also high-resolution orthos for city planning. In 2008 the National Land Survey of Finland (NLS) started a country-wide LiDAR project to upgrade their national height-model. Around 240 000 km2 of the total area 338 500 km2 of Finland has been surveyed until the end of 2013. The average point density in the NLS project is 0,7 points/ m2. Besides the new height model the data suits well to many other purposes like infrastructure planning and forest inventory. Since 2012 all LiDAR data, orthos and other mapping information of NLS has been public so, that anybody can download it easily and use free of all charges. Mobile mapping is a relativity technology. With success one has used the data in Finland to survey road surfaces for quality control and asphalt renovation by automated mobile control systems.
