Maps at 1 : 50,000 scale

The Czech Geological Survey is the first national geological survey to publish a complete edition of 1 : 50,000 scale geological and thematic maps covering its whole territory. This series consists of 1.651 maps which were issued progressively during the period from 1985 to 1998. Explanatory notes for each map sheet of this series were also printed in booklet form. They describe in detail the geological composition and structure of the area covered by each sheet, together with related aspects of engineering geology, economic geology, hydrology etc.

Geological maps at a scale of 1 : 50,000

These maps depict the geological composition and structure of the area covered by each sheet. The outcrops of the constituent igneous, sedimentary and metamorphic formations are shown, together with the position of faults, unconformities and other geologically important features. Thousands of observations obtained by drilling, geophysical measurement, geochemical analysis and the interpretation of remote sensing imagery have been used in compiling them. The geological map serves not only as a tool for understanding the geological evolution of a region and compiling related thematic maps, but also provides essential information for use in regional planning and development. The whole territory of the Czech Republic has been mapped at 1 : 50,000 scale.

Hydrogeological maps at a scale of 1 : 50,000

Hydrogeological maps provide information about the type, geometry and physical characteristics of the hydrogeological environment (aquifers, aquitards), areas of recharge and discharge and the quality and accessibility of ground water resources. These maps also provide information about the patterns of flow of groundwaters and their capacity to transport solutes, including contaminants. Since 1998, the whole of the Czech Republic has been covered by hydrogeological maps at a scale of 1 : 50,000.

Maps of geophysical fields and their interpretation at a scale of 1 : 50,000

These maps summarize the main results of geophysical surveys carried out in the Czech Republic. They include gravimetric, aeromagnetic, aero radiometric and gamma spectrometric maps. Geological features such as regional structures interpreted using a combination of geophysical methods are also shown. Those parts of the CR covered by the different categories of geophysical maps can be found in the list of published maps provided in the right menu on this page.

Mineral resource maps at a scale of 1 : 50,000

These maps show the locations of deposits of raw materials, and the resources they contain together with areas of inferred resources. They provide information about the exploitation of known resources of raw materials, as well as the potential for extraction in the future, about the rehabilitation of the landscape after mining, and about the impact on the environment.

Engineering-geological maps at a scale of 1 : 50,000

These maps provide information about the engineering-geological conditions especially in city regions. They are designed for use in regional and local planning, for example in the location of areas suitable for housing and recreational facilities, and the selection of sites for waste disposal. They are an essential tool for assessing the geological factors that must be taken into account when undertaking any engineering work and also for predicting the impact that engineering work will have on natural conditions during construction and after the facilities are put into use.

Maps of the geochemical reactivity of rocks at a scale of 1 : 50,000

These maps provide fundamental information about the distribution of elements and chemical components in the rock substrate. The maps have been compiled using archived and published data, together with information obtained from more recent analyses. Emphasis is placed on those reactive components in the rocks that influence the acidity and alkalinity of circulating ground waters. Carbonate rocks are designated the most reactive rocks because their active components behave as long-term inhibitors that neutralize the effects of acid pollution on water, soil and vegetation. Some silicate rocks with high contents of Na, K, Ca and Mg have a similar effect.

Soil maps at a scale of 1 : 50,000

These maps provide information about soil cap of the area. There is used the taxonomic soil classification system (type, sub-type,hydromorphic development, soil variety and form) as well as the soil-forming substrate. The CGS provides digitized soil maps also at a scale of 1 : 1,000,000 in the WMS format.

Soil-interpretation maps at a scale of 1 : 50,000

These maps show the potential of agricultural and forest soils. They contain information about the ecological and economic factors that govern the effective utilization of the soil resources in the Czech Republic. The maps also show the influence of relief to the vulnerability of agricultural and forest soils, the effects of acid precipitation and pollution, the boundaries of protected areas, the zones of protection around wells and water reservoirs, soils that are permanently or periodically wet, areas of periodic flooding, and areas where soils are at risk from water or wind erosion and salination. The boundaries of areas of protective forest, forests of specific types and forests endangered by industrial emissions are also shown.

Maps of surface water geochemistry at a scale of 1 : 50,000

These maps provide information about the degree of acidification of surface waters, the pollution of streams by heavy metals, contamination by atmospheric dust etc. Analytical data for 22 elements obtained using the most sensitive methods are presented in these maps enabling the purity of the waters in the surface drainage and water reservoirs to be assessed.

Maps of environmental geofactors : conflicts of interest at a scale of 1 : 50,000

These maps provide an immediate overview of the areas in which conflicts of interest could exist and the factors responsible. These maps, together with maps of significant landscape features, provide essential information about the requirements for environmental protection when plans are being made to develop a given area.

Maps of environmental geofactors: significant landscape features at a scale of 1 : 50,000

Maps of significant landscape features combine selected ecological information included in other maps of this series with specific data about the influence of human activity, as well as details of the assessment of vegetation condition of the mapped area (CHOPAV, LandCover, MZCHÚ…).

Maps of anthropogenic burden at a scale of 1 : 50,000

These maps depict the anthropogenic burden created by waste tips in relation to the geodynamic phenomena affecting a given area. These maps were compiled to enable assessment of the possible long-term negative effects of human activity on the environment without regard to rehabilitation and recultivation.

Maps of protected landscape areas at a scale of 1 : 100,000

These maps show all the categories of protected areas which were designated at the time of publication of a particular map. Maps of the currently protected areas can be found on the map server of the Nature Conservation Agency of the Czech Republic (AOPK ČR).

Explanatory notes to the 1 : 50,000 scale maps and directions for use

Explanatory notes were published only for some of the map sheets in the purpose-designed series of geological and ecological thematic maps at 1 : 50,000 scale. These are brochures which give an explanation of the geology of the area covered by the relevant sheet together with details of the hydrogeology, economic geology and other features of interest. Directions for using this series of purpose-designed geological and ecological thematic maps of natural resources explain the purpose for which they were compiled and the type of information that can be obtained from them. A glossary of terms used in the legends of individual maps is also given. Electronic versions of the Explanatory Notes and Directions for Use are accessible in the Digital archive (see below).
