Abstract

The canopy height models (CHM) derived on the basis of laser scanning technology become popular due to the several important factors. On the one hand, it demonstrates an accuracy of discrete laser points, while on the other hand there is a wide range of image processing methods for their analysis and extraction forest parameters. The remarkable feature of the CHM is that it contains the artifacts representing the local minima (or pits) within tree crowns. Currently there is no clear explanation for existence of these artifacts: they can appear from the data acquisition to the data processing. These artifacts are very unwanted, because they might badly influence the processing of the CHM, such as segmentation of crowns and calculation of forest parameters. In this paper, we propose an original approach to remove these artifacts during creating CHM in a GIS environment.
