3.2 Topography and cartography
The status of Unified National Map System (EOTR) sheets is as follows:
- in scale 1:200,000: 23 EOTR sheets (100%)
- in scale 1:100,000: 84 EOTR sheets (100%)
- in scale 1: 25,000: 267 EOTR sheets (25%)
- in scale 1: 10,000: 3425 EOTR sheets (84%)
The revision of these maps is inevitable with special attention on the 1:10 000 scale sheets.
In frame of the EU-Harmonisation Programme of the Ministry of Agriculture, the 1:100 000 scale EOTR sheets
have been digitized. Recently, the following products of the Digital Topographic Database (DTT-100) are
available:
- raster data of contour lines (84 sheets), planimetry (84 sheets), hydrography (84 sheets) and colour prints (84 sheets),
- vector data of contour lines (84 sheets), planimetry and hydrography (10 sheets),
- digital terrain modell (DTM with 100m *100m regular grid intervals).
A strategic plan of digitizing and receiving the 1:10 000 scale topographic base maps of Hungary has been
elaborated.
Mention should be made, products in digital form are also available on the market as it follows:
- The OTAB (geographic map database fulfilling the requirements of 1:200 000 scale, developed by GEOMETRIA
Systems House Ltd, on the base of 1:100 000 scale EOTR maps to provide background for GIS in the 1 :100 000
- 1:1 000 000 scale range (its size is about 35 Mbyte).
- The military DTA50 1:50 000 digital topographic database developed by MH KARTŰ, released later this year
including the Digital Elevation Model (DDM-50) in the Unified National Map System and in Gauss-Krüger
projection system.
