The harmonized geological map of Slovenia at a scale of 1:1,000,000 is a simplified version of the 1:250,000 scale Geological Map of Slovenia (Buser, 2009). The latter was compiled from the Basic Geological Map of Slovenia at a scale of 1: 100,000 (contributed by various authors between 1960's and 1980's and updated with new information gathered by S. Buser). The map is basically lithostratigraphic. The two layers incorporated in the map are lithostratigraphic units and major faults. The faults depicted on the map were selected using two criteria; regional extent and tectonic importance. The map presented here was edited specifically for the purpose of the OneGeology-Europe project by M. Bavec, M. Novak, M. Poljak, M. Trajanova and D. Skaberne.
                  The Basic Geological Map of Slovenia as a part of joint Basic Geological Map of SFR Yugoslavia presents lithological and stratigraphic characteristics of rocks, their relationships, age and other. It is a key to the understanding of the geology of Slovenia. It consists of 23 sheets at a scale of 1: 100,000.

                  Layer Geomorphologic Features shows the location of various types of geomorphological phenomena. Only point data are included.
The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. These maps represent the expected isoterms at a depths and are derived from Geothermal maps - Expected temperatures , which are made with data from 302 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course of the isotherms is a result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths.
                  Geophysical cross sections show the geophysical characteristics of the sediments and bedrock at depth.

                  Karte prostorske porazdelitve vrednosti spremenljivk vezanih na temperaturo zraka so narejene na osnovi meritev klimatoloških meteoroloških postaj, ki so v obravnavanem obdobju neprekinjeno delovale vsaj deset let. Za računanje vrednosti spremenljivk vezanih na temperaturo zraka v pravilni mreži z ločljivostjo 100 m x 100 m je bila uporabljena metoda optimalne prostorske interpolacije, ki upošteva povezanost obravnavane spremenljivke z nadmorsko višino in preko izbrane okolice upošteva tudi vpliv mikrolokacije. Zaradi majhne gostote mreže opazovanj, je vpliv mikrolokacije možno upoštevati le v manjši meri.
                  Layer shows discontinuities in the geological structure, and characterizes them according to their type and observation method.
                  Gladina podzemne vode (hidroizohipse) predstavljajo srednje vodno stanje gladine podzemne vode v plitvih opazovalnih objektih (plitva gladina podzemne vode). Meritve so bile izvedene v zelo visokem (24.10.2014 - v okviru projekta Izdelava metodologije in pilotnega vnosa hidrogeološke karte v M 1:25.000) in zelo nizkem (22.11.2011 - v okviru Projekta INCOME) vodnem stanju, srednja vrednost meritev. Pomembno: meritve so bile izvedene v času črpanja v Vodarni Brest.
