The 1:10 000 land use map in paper is secured from the Region Land Office,
Koma´rom. After scanning and knowing the co-ordinates of the field borderline, four
points with known co-ordinates were identified in the map by means of a program
called Wgeo. By doing this, a twf file*/a file belongs to the tif file*/was generated.
The AGRO-MAP Professional software has the transformation equation, which is
required for the transformation from WGS 84 GPS co-ordinates to EOV (uniform
nation-wide projection system), thus the borderline co-ordinates recorded by GPS
could be handled in the EOV system. The database of the map with tef extension was
imported into the AGRO-MAP Professional program and the field borderline could
be inserted in the map as a new layer (Fig. 3).
