Ac­cur­ate geoin­form­a­tion for forestry

Spatial geoinformation is a necessity for cultivating sustainable natural resource management and a green economy. Airborne laser scanning (ALS) has enabled a technological leap forward to further the acquisition of detailed spatial geoinformation. By using ALS, one can collect geometrically accurate point clouds. These 3D data sets that use single- or multi-temporal point clouds enable a wide range of applications in the field of natural resource management. Adding a time dimension provides 4D geoinformatics. Multi-temporal geodata offers information about the history of our environment, and the 4D data can be used in modeling and simulating the future.
