摘要

The civil survey office of Bulgaria (now Main Department of Cadastre and Geodesy at the Ministry of Regional Development and Construction) began the compilation of a large-scale topographic map in 1954, which was completed in 1984. About 90percent of the map for the intensive activity regions of the country is at scale of 1:5000 and about 10percent for the high mountain and forest regions is at scale of 1:10 000. The contour interval is 1, 2, 5, and 10 m depending on the scale and the terrain slope. The map is three-coloured and the sheets are 50X50 cm in size. Gauss-Krueger Projection, Plane Coordinate System 1970 and Baltic Sea Level Datum are used. An average of 1 to 2 triangulation points are to be found in one 1:5000 map sheet. The map is produced and periodically revised by aerial photogrammetry. For some specific purposes (mainly designing of linear, hydro-technical and industrial projects) maps at scale of 1:2000 and larger are made. Maps and orthophotomaps at scales from 1:10 000 to 1:500 for the needs of rural and urban cadastre are produced.
