e At the territory of Eastern Croatia the map contents 
correspond to the situation in 1982-1984. 
The topographic map at the scale of 1:200 000 (TK 200) was 
made during the period 1972-1975 (the first edition) on the 
basis of the map TK 100. In 1985 the second edition was 
published, supplemented on the basis of the new edition of 
TK 100. For the area of Croatia this edition has the following 
characteristics: 
e At the territory of Eastern Croatia the map contents 
correspond to the landscape situation in 1984. 
e At the territory of Western Croatia the map contents 
correspond to the situation in 1985. 
The general topographic map at the scale 1:300 000 was made 
during the period 1984-1985 on the basis of the second edition 
of TK 200. The general topographic map at the scale of 
1:500 000 in Lambert conformal conical projection (PTK 500) 
was made during the period 1979-1983. On the basis of the new 
edition of TK 200 the amendment was published in 1989 and 
the second edition printed. 
More information about geodetic works, land surveying, 
production and maintenance of maps under the supervision of 
former Yugoslav Army can be found in the overview Geodet- 
ska sluzba JNA (Peterca, Colovié 1987). 
2.4 Topographic map of Croatia in digital form — the first 
temporary edition 
The Republic of Croatia was left without the reproduction 
originals of topographic maps after becoming independent. It 
was decided that the reproduction original copies would be 
generated from the existing topographic maps 1:25 000. 
Although the contents of the existing topographic maps were 
old, the print of the reconstructed sheets with new external 
description without the revision of the contents was a necessary 
and temporary solution. The production of the reproduction 
originals was done by means of digital procedures of scanning 
the multi-colour print, separating it into layers according to the 
colours used in printing. Digital records were first in the PDF 
format, and later they were transformed into TIF. The new 
coordinate grid was based on WGS 84 system and available in 
DXF or DWG formats (Landek, 2001, 2003). 
The same procedure was also applied on topographic maps at 
the scales 1:100 000 and 1:200 000. 
2.5 Production of the new Croatian topographic map TK 25 
SGA systematically performs the cyclical aerial survey of 
Croatia since 1996. The scale of the survey is 1:20 000, the 
images are black and white or coloured, and the size of 23x23 
cm. SGA sells copies and contact copies, as well as scanned 
aerial photographs in various resolutions (Landek, 2001, 2003). 
The data processing is performed by digital methods in order to 
create a high quality base of topographic data for the 
establishment of information system and digital relief model. 
The block adjustment is performed by the bundle of rays. The 
photogrammetric plotting is on analogous stereo instruments, 
and mapping with Bentley's MicroStation. Mapping is in two 
separate files (the situation is separately mapped, and then 
separately the elements for the production of digital relief 
model). The computation of digital relief model (DMR) in the 
166 
  
    
production of TK 25 is made using the program SCOP. The 
topographic contents are available in the formats DGN/DXF, 
EXPRESS, and the presentation of heights in the formats 
SCOP-DTM DXF, WINPUT, ASCII, DGN.

Figure 3. Part of the new Croatian topographic map at the scale 
of 1:25 000 
More details about the production of new Croatian topographic 
map at the scale of 1:25 000 can be found in the report by S. 
Lemajic (1998). 
According to the Program of State Survey and Real Estate 
Cadastre for the Period of 2001-2005 (Hrvatski drZavni sabor, 
2001), the production of all 594 sheets of TK 25 will be 
completed during that period. 62 sheets have been completed 
until July 2003 (Fig. 3). 
2.6 General topographic map of Croatia at the scale 
1:500 000 
In 1993 the map of the Republic of Croatia was made at the 
Institute for Cartography at the Faculty of Geodesy in Zagreb 
presenting the county areas at the scale of 1:500 000. The map 
was made for the Ministry of Defence. In 1995 the air 
navigation map was made at the Institute for Cartography at the 
Faculty of Geodesy, University of Zagreb, published by the 
Ministry of Defence on two sheets (Zagreb-Zadar and Osijek- 
Split) at the scale of 1:500 000, and in the same projection and 
with the same parameters as the earlier mentioned map of 
county areas.
