Höhendarstellung in OL-Karten mithilfe von Airborne Laser-Scanning Representing the relief of Orienteering maps with the aid of airborne laser scanning Höhendarstellung in OL-Karten mithilfe von Airborne Laser-Scanning Thomas Hohl Gymnasium Kirschgarten Basel

Airborne Laser-Scanning Laser impulse in forested areas first received impulse last received impulse

Airborne Laser-Scanning Method of analyzing GRID TIN Laser raw data Contour lines

Comparison of contour reliefs Criteria for the test area existence of an orienteering map existence of a photogrammetric base map an area with detailed terrain (depressions, knolls, rocky features) O-maps 'Leutschenberg-Schafmatt' Area 2km x 2km =4km2 Coordinate 636/251 638/249 Geoinformationsystem (GIS) Idrisi 2.2 and ArcGIS 8.3

Comparison of contour relief Conclusion 2,5m-DTM - In detailed terrain not sufficient → 1m-DTM - precise contour lines in dense vegetation Photogrammetric base map - not suitable in dense vegetation and north sides of hills very good representation of the terrain in open terrain O-map - often features are represented with objects instead of contour lines  bad legibility

Comparison of contour reliefs Conclusion positive negative DTM very precise position accuracy - pseudo features - dithering contour lines - completeness - representation without O-symbols - good for relief representation only eliminate features, no new measuring Photogrammetric base map - representation with O-symbol - inprecise - uncompleted - new measurements necessary

Conclusion Advantages of laser air borne scanning 1. Saving of time in the terrain because of its availability without interruption and precisness (elimination instead of measuring). 2. Raw-data all over Switzerland available. Time consuming work to find photogrammetric pictures are not any more necessary 3. Significant reduced costs compared to photogrammetric base maps. 4. Data are available rapidly. 5. Combination with orthophotos possible (georeferenced) Disadvantages of laser air borne scanning 1. Base map without O-set of symbol 2. A detailed contour relief could easily lead to an over crowded and badly generalized map image.
