4. METHODS
After the manually drawn and coloured vegetation map was completed on a 1:10,000 scale, this
map was decreased in scale to 1:25,000 to coincide with the original 1:25,000 regional map. Both
maps were then scanned in 200 dpi with "jpeg" format to enable the authors to load them to a
computer and do manipulations. Arcview GIS Version 3.1 was used. Though an appropriate size
of a digitising table was available for the project, because of the steep terrain conditions and since
user must have relied upon the limited magnification capacity of the table's mouse, this option was
omitted. If the digitising was done using the mentioned digitising table, due to the fact that there
would have not been a reliable base map readily viewable through the screen, the unavoidable
mistakes to be done during the digitising would have directly transmitted to the pertaining layers.
Hence the digitising was done through the screen on the “jpg” images. The unlimited magnification
capacity and flexibility of the software enabled the authors to zoom in as much as needed and to do
corrections as much as necessary during the digitising. Positional accuracy in this way was the
same as what was on the original map and the manually done vegetation map. 7 different layers
were created. They were as follows:
Circumference of the region, the outer extend of the whole study area — boundary map.
Contour lines spaced at 10 m intervals — contour map.
Stream, with its all year running and dry in the summer tributaries — creek map.
Sample points taken at — points map.
Sample points taken + soil profile — points+profile map.
Plant societies, each of the established 15 land cover types — vegetation map.
Transportation network, unpaved but year round useable roads — road map.

After these maps were created, a user, forester, will be able to see and decide what kind of
vegetation live in the district what can be done in the future, what kind of forest management
practices can be performed and so on. Changes in terms of the vegetation types and extends can
always be updated as long as a reliable data sources is available (Figure 3).
