Slope based grid creation using interpolation of LIDAR data sets

Popis výsledku v původním jazyce

This article proposes a new approach of DTM creation from irregular LIDAR data scan. It shows the new way how to utilize GIS results in the 3D modelling branch. LIDAR has a form of digital model of relief which does not include artificial objects on thesurface. DEM is created on the basis of individual points and their elevation values and is further used for segmentation and classification of the terrain. Key attribute for this operation is computation of the slope in the area of interest. Resulting classes are used as vector outlines. These outlines are intended to divide the point cloud into groups. Each of them has specific requirements for resolution. Flat areas can be modelled with less detail whilst hilly regions with sharp elevation changes require higher resolution. LIDAR input is processed by chosen interpolation method, in this case IDW and Renka-Cline algorithm. Irregular structure of the point cloud is converted into regular grid of points. This process is semi-automatic.
