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.

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.
