The importance of a GIS has not known widely in 
Turkey although some activity in different agencies 
has already been initiated but not yet completed. 
On the other hand forest management activities in 
Turkey back to 1924 and has made considerable 
progress since then using aerial photographs and 
sateilite imagery but not in GIS. According to the 
law issued in 1924, accepted is the principal to 
manage all the forest in Turkey by use of 
management plans. It is in 1946 that the forest

the annual growing stock and increment in a 
working cycle, tree species in a stand class. etc. 
Neither conventional maps nor forest inventories 
are sufficient enough to supply locational and 
descriptive forest data. Updating of these maps and 
inventories is rather cumbersome and time 
consuming. Although some CAD and DEM systems 
are able to manipulate this type of data and solve 
problems to some extent, the relationship between 
these two different types of data can not be 
created. A GIS applicates in forest management 
seems to be an obvious choice, for it is able to 
manipulate locational and descriptive data and the 
management plans for Turkey were completed, relationships between them, as well, even 
being the base to the inventory and statistics of the dynamically.
