Nationwide Generation of Height Data from Airborne Laser Scanning and Other Sources

12 - 13 January 2016

January 12th and 13th, 2015 at the premises of the County Governor of Vestfold in Tønsberg, Norway,  EuroSDR and the Norwegian Mapping Authority organized the workshop “Nationwide generation of height data - from Airborne laser scanning and other sources”

The objective of this workshop was to share experiences and knowledge gained with nationwide generation of height data. Identify common challenges and discuss possible solutions, identify fields of possible cooperation.
