WFS service provides access to basic information about mineral deposits, mineral occurrence and mining activity in Slovakia. Service was created in framework of the M4EU project.

The first version of the contiguous digital map was compiled by Š. Káčer et al.(2005) under the terms of the geological project Digital Geological Map of the Slovak Republic at a scale of 1: 50 000. In addition to areal, line and point information, the following separate layers are available: a list of the background documents, classification of the data in terms of quality, a review of the scheme used for classification of geological units and structures. The areal information provided on the digital map includes: the unified legend and the original legend showing the characteristics and occurrence of individual lithotypes across the whole territory of Slovakia.

Geological map of the Quaternary of Slovakia at a scale of 1 : 500 000 compiled by J. Maglay et al. showing different types of Quaternary deposits according to their origin. The map plainly shows the spatial distribution and surface extent of all primary, as well as some selected "transitional" genetic types of Quaternary sedimentary and volcanic rocks in Slovakia. It presents a basic picture of the sequence of their evolution and their patterns of distribution and deposition. A component of the map is a lithostratigraphic classification of the Quaternary of Slovakia.

Geological Map of the Western Carpathians and Adjacent Areas at a scale of 1 : 500 000 compiled by J. Lexa et al.( 2000). The map contains both polyline and polygon layers. The basis used for the compilation of this map is the Geological Map of the Slovak Republic at a scale of 1:500 000, compiled by A. Biely et al.(1996) with amendments derived from the geological maps of the neighbouring countries.
