Methodical investigations for digital forest land-registration in Greek

The forest land-registration as a part of the national land-registration is not only a guarantee of property but supports as well an ecological-econom ic forest management. In Greek the implementation of the forest land-regist ration is delegated to the creek forest administration in co-operation with the land-registry office. The Greek forest regions cover nearly 70% of the land and they are mingled with agricultural used at eas. Only with terrestrial methods and without th e utility of modern photogrammetric methods a land registration is not to b e accomplishing before long. In the present examination it is scientifically investigated in which exten t the two modem aerial photo analysis methods, analytical photogrammetry an d,,softcopy"-photogrammetry, can be used to solve the task and which intens ification in efficiency the two techniques will gain. The results are of great promise. The accuracy of the two photogrammetric m ethods is completely sufficient for a forest land-registration. They feasib le a modern digital forest land-registration and their area accomplishment is dependant from the topographic conditions as well as from the parcel siz e and distribution nearly 6 to 8.5 times higher than the purely terrestrial land-registration survey. Additionally, the aerial photographs are juridic al important documents, which can be brought up at any time in cases at iss ue and they present semantic information about the forest areas, which are of great importance for all forest activities.
