These special techniques and the results of these projects will be presented during this tutorial. Technology, key features, typical applications, and data post processing are addressed. To orientate the recordings of different positions of a terrestrial laser scanner, absolute or relative to each other, the point cloud is visualized as an image, allowing the user to identify homologous points. In the latter case, merging data of adjacent strips' shows up discrepancies in Z which probably stem from orientation deficiencies. A method to minimize such discrepancies by block adjustment using polynomials for connecting the laser scanner strips is demonstrated.
Special algorithms are necessary for classifying and filtering laser scanning data.
Techniques such as rain simulation allow for geomorphologic enhancement of the interpolated surface. Manisided tools to support data and surface analysis are also inevitable. Accuracy assessment is of special importance. These special algorithms will be explained and demonstrated in detail. N. Pfeifer, Ch.
