Photogrammetry in Forestry- Tool for Effective Inventory and Planning

The application of photogrammetry is not as usual in forestry as it is in other fields. The presented paper shows one of a variety of possible applications belonging to the field of forest inventory. The interpretation of colour infrared aerial photographs in combined with the use of photogrammetry enables one to ascertain data that is needed for planning in forestry. The obtained information, stored and handled in a Geographic Information System (GIS), leads to maps representing the actual situation of a forest district. These maps are more accurate and detailed than this is possible using the conventional mapping procedures in forest management planning. The map information and data which has been additionally interpreted and measured from aerial photographs supports the forest manager and is advantageous during the fieldwork. Due to this fieldwork is less time-consuming. The presented procedure provides the forest management and the forest rangers in a rational and fast manner with actual information about their district. The availability of the data in a GIS enables a more thorough work by using this information selectively and orientated to actual problems as they arise. 1
