Map server application creates an overview of the significant geological localities in the Czech Republic. The application presents sites in the Czech Republic which demonstrate extremely diverse geological features, occurrences of significant rocks, minerals and fossils. The application enables the user to search according to attributes of the localities, administrative units, map grids etc. Other map layers are also available (geological maps, etc.).
The works on the database of important geological localities started in the Czech geological institute in 1992 in sequence to creation of the registry of protected geological localities (together with AOPK).
During years 1997-1999 was the geological localities file transformed in digital form (MS Access database). One year later it was transformed in the central data storage of the Czech Geological Survey (ORACLE database). Locations of the geological localities have been subtracted from maps at a scale of 1:50 000 and smaller. At present, updates of database and precising of coordinates (scale 1 : 25,000) are going on. English version of the application was made and published in 2014. The Czech version of the map application was remade into Web AppBuilder and published in https mode on 15.11.2017; the english version was remade on 24.4.2019.
