Researches on the optimal methodology for creating geographic databases for forest management planning

摘要

Steps for creating GIS databases for Forest Management Planning:1. Scanning of forest management planning maps, equipped by forest plan-ning specialists. Output: cartographic digital database in raster form2. The raster maps are projected into local coordinate system (Stereografic1970)3. Color strata, corresponding with cartographic elements, are extracted foran efficient vectorisation4. Cartographic feature extraction, from raster maps, into vector form5. Digital cartographic database and management planning attributes inte-gration6. Database management:6.1. Geodatabase querying6.2. Forest Management planning maps and plotting6.3. Digital terrain model7. CD recording of the geodatabaseComplex exploitation of the geodatabase within GIS offers huge possibilitiesincluding: fast data query, extraction and analyze, rapid localization of forest manage-ment units according to specific criteria, thematic maps (including forest man-agement planning maps) build, 3D models, etc
