Abstract

Use of laser data to update land resource map AR5
Track: Lidar and 3D Mapping
Authors: Halvard Bjerke

This presentation summarizes the experience with the use of LiDAR to identify opportunities to support the updating of land resource map AR5 (Norwegian Forest and Landscape Institute).

ArcMap combines the AR5 with the established raster images. Based on the knowledge of the various information from LiDAR, raster images are selected due to suitability for their purpose and an overlay analysis draws out the areas of interest. Several visual observations of the raster images are also done in ArcMap where the focus is to demonstrate the quality of the pictures provided from LiDAR.

The results from the combination of raster images in ArcMap show that the heights in both forests and fully cultivated lands are detected. Buildings can also be separated from the vegetation by looking at different pulse returns.

I think this presentation will give the audience a good view of the possibilities LiDAR has in the GIS world.
