Individual content elements were scanned from basic topographic maps at scales 1 : 5000 and 1 : 10 000,
topographic maps at scales 1 : 25 000 and 1 : 50 000, large-scale maps of Slovenia at scales 1 : 250 000,
1 : 500 000 and 1 : 750 000. The content of individual layers depends upon the existing originals of
individual maps.
The first scanning was conducted with a resolution of 200 dpi in 256 shades of gray; the data was processed
to a resolution of 300 dpi and recorded in single-bit format. The original data format is TIFF, Group 4,
TIFF Strip Size - Infinite. Since 1997 the scanning of revised maps has been implemented with a resolution
of 400 dpi in 256 shades of gray in the TIFF format, followed by the oversampling from 400 dpi to 300 dpi.
Content of map raster data – All scanned images contain only the map content that occurs interior to the
map sheet border. All content occurring exterior to the map sheet border is left out in order to allow the
possibility of joining sheets of basic topographic maps. Scanned images are recorded in the form of a
rectangular matrix.
Names of scanned image files are formed in line with the instructions of the Surveying and Mapping
Authority of the Republic of Slovenia. The description of the filename system is given below.
Geodetic basis

The scanned image coordinates are given in the Gauss-Krueger projection. The reference point is
located in the left upper corner of the sheet. The coordinates are recorded in a file labeled
sheetname.TFW (world file Arc/Info PC and WS).

ASCII files including coordinates of corners of trigonometric sections and map sheets are used for
geo-referencing maps in raster form. The filenames used are given below:
- for trigonometric sections - SEKCIJE.TXT,
- for national topographic maps at 1 : 25 000 scale - TK25KOO.TXT,
- for topographic maps at 1 : 50 000 scale - TK50KOO.TXT,
- for national topographic maps at 1 : 50 000 scale - DTK50KOO.DOC,
- for large-scale maps of Slovenia - PKKOO.TXT.
Data transfer formats: Standard raster formats (TIFF/Group 4, PCX, and RLC).

Orthophoto at a pixel resolution of 0.5 m and plots generated at 1 : 5000 scale have been produced on the
basis of aerial photographs at scales from 1 : 17 500 to 1 : 25 000.
They are produced on photogrammetric workstations. The rectification of orthophoto with 0.5 m pixel size
was done on the basis of the 25 m digital terrain model.
Data content – The area of a single orthophoto corresponds to the area of a map sheet at 1 : 5 000 scale.
Orthophotos are recoded in the form of a rectangular matrix. The black and white file contains an 8-bit per
pixel image (256 shades of gray) and the coloured file a 24-bit per pixel image (16 milions of colours).
The names of digital orthophoto files are formed in line with the instructions of the Surveying and
Mapping Authority of the Republic of Slovenia. The description of the filename system is given below.
Geodetic basis
 The coordinates are given in the Gauss-Krueger projection. The reference point is located in the left
upper corner of the sheet. The coordinates are recorded in a file labeled sheetname.TFW (world file

3.
The Register of Geographical Names uses cartographic sources to capture only the names with temporal,
historical, ethnological and social identity.
The names of individual objects may differ due to different cartographic sources. The main objective
underlying the setup of the Register of Geographical Names is the standardization of the written forms of
individual names. Standardization is used to identify and prescribe the written form of individual
geographical names.
The Register of Geographical Names has been created to meet three precision levels:

1 : 5 000 scale (REZI 5). Data is captured from TTN 5 and TTN 10.

1 : 25 000 scale (REZI 25). Data is captured from DTK 25.

1 : 250 000 scale (REZI 250). Data is captured from PK 250.

Designation of individual map sheets at 1 : 10 000 scale
The system of filename formation used for files of basic topographic maps at 1 : 10 000 scales differs from the
filename of a basic topographic map at 1 : 5 000 scale only in the character string designating the trigonometric
section. The numbering of sheets at 1 : 10 000 scale is conducted for two trigonometric sections. Therefore, the
general sheet designation also includes numbers identifying the two rows (e.g. 21-22). Since the filename can
accommodate only two fields, these will be formatted so as to subtract 18 from the lower (odd) row number. The
most southerly row of trigonometric sections in Slovenia is labeled with the number 19. If the sections 19-20
include sheets at 1 : 10 000 scale, the number 01 is assigned to identify the trigonometric section type.
In compliance with the procedure described above, the character string B0711 makes part of the name
identifying the TOLMIN - BOVEC 11 sheet.
The first three character positions of the name provide the general designation of the trigonometric section –
designation of column and row.
Example: B07 is the general designation of the TOLMIN - BOVEC trigonometric section.
Division into trigonometric sections:
The fourth and fifth character
position of the sheet name contain
the sheet number of the basic
topographic map at 1 : 10 000
scale. The sheets are numbered
within two trigonometric sections
with numbers from 1 to 25, as
illustrated below with the
example on the TOLMIN –
BOVEC trigonometric section.

Designation of individual map sheets at 1 : 50 000 scale
The designation of individual
sheets of topographic maps at
1 : 50 000 scale is formed in line
with
the
existing
general
designation of topographic map
sheets. The area covered by a single
civil map sheet at 1 : 50 000 scale
(TK 50 GZ) equals the area covered
by two military map sheets at
1 : 50 000 scale (TK 50). Therefore,
the first two character positions
contain the designation of a
topographic
map
sheet
at
1 : 100 000 scale. These are
followed by an underscore in order
to allow name distinctions between
topographic maps at 1 : 50 000 and
1 : 25 000 scales. The underscore is
followed by the designations of two
map sheets at 1 : 50 000 scale.
In compliance with the procedure described above, the string 13_34 makes part of the name identifying the
LJUBLJANA sheet.
The graphics overview of the grid of topographic map sheets at 1 : 50 000 scale contains the general designations
of individual sheets.
