* automatizovaná tvorba a generalizace kótovaných bodů * co je master database? * __hiearchical classification__ * **special interest points** * defined by data producer * related with map names (vyhledává do v databázi) * **geomorphologic interesting points** * terrain points - peaks, mountain passes, depressions * kategorizace: conic, assymetrical, open, closed * they didnt use DEM but TIN, because of some difficulties to this methodology * One is that the centre of a pixel in raster data can not be coincident with the exact position of the spot height and the location of the pixel containing the spot height is unclear * in raster format, each pixel of the DEM must be analyzed, while when using a DEM in TIN format, the analysis can be specifically restricted to the spot heights. Therefore, the use of a DEM in TIN format reduces substantially the computation time * peaks: * bud podle vyhledávací oblasti, hledám nejvyšší bod * nebo podle tvaru Base Contour Line (je nemenší vrstevnice, obsahující jeden vrchol) * deprese: * podle minimálního souseda * **remainder points** * There must be a spot height approximately every 1200 meters on the roads * The input spot heights placed on the intersection of roads are considered as preferred spot heights ----------- * simplification,amalgamation, exaggeration, collapse, displacement * geodetic points, * points located in crossroads, * points in urban areas, and * points near roads, near generic toponyms and near places of touristic interest (like monuments, ruins, viewpoints, springs, etc.).
