elevation differences the orthophoto-maps are composed with the Topocart- 
-Orthophot instrument combination. 
Relief plotting is identical with the universal method, but here the topograph 
has to qualify the planimetric plotting in the site, and perform control 
measurements in the relief. About 90 per cent of the country's territory has 
already been mapped in 1:10000 scale by the phototopographic technique. 
Parallel to the 1:10000 photogrammetric survey the revision of the old 1:10000 
maps, too, is continued with photogrammetric materials and methods, of 
course, 
4.2 Cadastral basic maps, (for agricultural, registering, urban and rural 
community development purposes) are prepared in 1:1000, 1:2000, and 
1: 4000 scales, 
4.3 Towns and other urban settlements are surveyed in a scale of 1:1000, 
while the aerial photography scales vary between 1:4000 and 1:6000. 
Determination of the so-called "F-points" is accomplished by aero -triangulation. 
These photogrammetric points are signalized and stabilized in the site prior to 
photography. Planimetric plotting is made on correctostat paper or dimensionally 
stable plastic material, Relief plotting is executed similarly on a plastic material 
placed over the basic sheet, by making use of the in-site determined height 
photocontrol points, with 1 m contour lines, and spot height measurements, 
Smaller communities are mapped 1:2000 with the technology described above. 
The photogrammetric plotting is checked upon by in-site measurements, where- 
after chsdfication and completion are followed by fair drafting. 
4.4 The intensive development of agriculture necessitated the cadastral 
resurvey of vineyard, orchard, and arable land areas. Vineyards and orchards 
are mapped in general in a 1:2000, while the fields in 1:4000 /seldom 1:2000/ 
Scale. Here, too, aero-triangulations are performed, partly for F -point 
determination, and partly for the photocontrol point recuirement of the plotting
