Název v původním jazyce

Optimization of digital terrain model for its application in forestry

Popis výsledku v původním jazyce

Digital terrain model (DTM) represents a very important geospatial data type. In the Czech Republic, the most common digital contour data sources are the Primary Geographic Data Base (ZABAGED), the Digital Ground Model (DMÚ25) and eventually the RegionalPlans of Forest Development (OPRL). In constructing regular raster DTM, the initial process requires interpolation between the points in order to estimate values in a regular grid pattern. In this study, constructions of DTM from the above mentioned data were tested using several software products: ArcEditor 9.0, Atlas 3.8, GRASS 6.1, Idrisi 14.02 and TopoL 2001. Algorithms parameters can be optimized in several ways. In this sense the most useful operations proved comparing the first and second derivative of DTM and its real appearance in terrain and using cross-validation procedure or terrain data measurements to compute and minimize the root mean square error values (RMSE). The ZABAGED contour data provided the best results, with so
