data were needed to meet the TOPO 5 requirements. Final result 
did not justify time and money spent. The quality and 
harmonisation of data were also not satisfactory. Therefore the 
decision was made to acquire all vegetation data by 
photogrammetric methods. The existing ERZ serves only as 
help interpretation of data. 
Different interpretation of attributes and their values in different 
situations generated unnecessary errors and necessitated 
multiple checking, which again required more time than 
originally planned. It became evident that with large number of 
interpreters it is necessary to exactly define all possible 
combinations of attributes and their values to exclude 
misinterpretations of an individual interpreter and possible 
dilemma about selection of correct data. 
Surveying and Mapping Authority of Republic of Slovenia is 
planning to cover all major urban areas with the TOPO 5 data. 
These areas represent about 30% of the territory of Republic of 
Slovenia. That means approximately 1000 sheets of which a 
little more than 300 have already been produced.

2.1.2 Geodetic Template for Spatial Planning. One of the 
main reasons for setting up TOPO 5 was to enable production of 
standard products as a result of database visualisation. The first 
such product is Geodetic Template for spatial planning. The 
207 
Surveying and Mapping Authority of Republic of Slovenia 
started this project in the year 2002 with the intention to provide 
unified geodetic template for spatial planning at local level 
(Petrovic et al, 2002). Geodetic templates for spatial planning 
are elaborated gradually and it is expected to cover all major 
urban areas in the Republic of Slovenia within a few years. 
Geodetic template for spatial planning includes topographic and 
cadastral data. Topographic data is adopted from existing 
TOPO 5. Only selected topographic features are included (see 
Table 2). Relief data is added in a raster format.

DOF is the basis for review of the existing TOPO 5 if it is more 
recent than TOPO 5. All updates are taken into consideration 
for the production of geodetic template and for spatial planning.
