The GEOBG500 dataset was created in 1995 by digitizing the paper version of the Geological map of Bulgaria at a scale of 1:500 000, that was published in 1989. This consists of 2 flat coloured sheets covered the whole territory of Bulgaria. The map has been produced in a combined Bulgarian-English edition and was compiled using the Geological Map of Bulgaria at a scale of 1:100 000 as a base, combined with data from the National Geofund. The dataset is digitally integrated and available in MapInfo format.

The GEOBG100 dataset was created during the period 1995-1997 by digitizing the paper version of the Geological map of Bulgaria at a scale of 1:100 000. This consists of 86 coloured flat sheets, covering the whole onshore territory of the country. The map is available in a Bulgarian or in an English edition. The dataset is digitally integrated and available in MapInfo and ArcGIS formats.
