• 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.).
