The data were obtained in the course of implementation of the “Atlas of lithological parameters of surface sediments of the southern Baltic Sea with special emphasis on geological and mining conditions of occurrence of aggregate deposits”, which was developed by the Polish Geological Institute and released in 2005. The Atlas includes maps of main grain size classes, mean grain size and sorting as well as content and composition of heavy minerals. The analysis of lithological parameters was the basis for determination of prospective areas of occurrence of aggregate deposits in Polish maritime areas.

Geological -tourist map of "Mierzeja Wiślana" Landscape Park in scale 1: 60 000 is one of the 5 part series of maps, commissioned by the Ministry of Environment, a project financed by the NFEPandWM

Data were derived from the study: "Recognition and Visualisation of the Geological Structure of the Gulf of Gdańsk for Natural Resources Management", which was developed by the Polish Geological Institute and released in 2008. The geological research carried out in the framework of the project aimed to specify the geological recognition of the Gulf of Gdansk and to visualize the morphology, sediment distribution, dynamic processes occurring at the bottom and the Quaternary sediments structure, with special emphasis on the Late Glacial and Holocene. One of the most important tasks was to obtain current detailed information about the geochemical status of the surface sediments. The seismoacoustic methods used have identified geological structure to a depth of 10 to 50 m b.s.l., depending on the geological structure of the bottom and the water depth.

Geological-tourist map of Ojcow National Park in scale 1: 25 000 is one of the 10 part series of maps, commissioned by the Ministry of Environment, a project financed by the NFEPandWM.

Maps showing the feasibility of borehole heat exchangers, considering chosen environmental conditions. Maps are the result of spatial analyses showing 3 types (classes) of areas with the division whether there are contraindications to the construction of a boreholes for ground source heat exchangers (GHE): - installation without contraindications - no adverse environmental conditions; - conditional installation - construction of the installation is conditionally possible (local environmental conditions should be analyzed in detail in the geological operations project and taken into account in the technical design of the GHE); - obviously contraindicated installation - execution of the installation is possible with evident contraindications (due to extremely unfavorable environmental conditions). In addition, an area class of ‘surface water’ was distinguished. Maps were produced as part of a project funded by the National Fund for Environmental Protection and Water Management entitled: ‘Assessment of the energy potential and environmental conditions of low-temperature geothermal energy’ carried out between 2017 and 2022.

The GIS data derived from the "Geological Map of the Polish maritime areas for the purpose of so-called Additional Military Layers" issued by the Polish Geological Institute in 2012. The study on a scale of 1:200 000 shows lithological diversification of surface sediments within the Polish maritime areas according to the R. L. Folk classification (1954) distinguishing 15 different lithological types of sediments. Additionally, the areas where boulders occur in the midst of sand and gravel deposits were identified. The map was prepared according to the defence standard NO-06-A058-5.

The Map of Groundwater Utilization Classified as Mineral Resources in Poland was developed by the Polish Geological Institute – National Research Institute. The first edition was published in 2015 and included information on medicinal, thermal, and brine waters as of the end of the previous year. Due to the dynamic increase in the number of documented deposits and resources, as well as significant interest from users, the map is updated annually and is available in digital format. Each edition of the map provides information on the occurrence of medicinal, thermal, and brine waters, which, according to the Geological and Mining Law, are classified as mineral resources. It includes their physicochemical characteristics, exploitable resources, methods and intensity of utilization, as well as planned investments related to their extraction. Additionally, the map presents data on areas particularly favorable for the exploration and extraction of these types of waters.

Maps showing average values of thermal conductivity of soils and rocks, expressed in units of W/(m*K), for the 0-40 m depth interval. Maps were created on the basis of a numerical, three-dimensional model of geological structure (base model), which was then filled with geological-thermal series with assigned values of thermal conductivity rate expressed in units [W/m*K] (parametric model). The parametric model was used to calculate the average value of thermal conductivity of soils and rocks at each point of the studied area and up to the chosen depth level. Maps were produced as part of a project funded by the National Fund for Environmental Protection and Water Management entitled: ‘Assessment of the energy potential and environmental conditions of low-temperature geothermal energy’ carried out between 2017 and 2022.

The Database of Groundwater Classified as Mineral Resources contains information regarding wells and springs where waters classified as medicinal, thermal, and brine waters are extracted. The data collected in the database includes the location of intakes, measured and calculated hydrogeological data, basic drilling and lithostratigraphic information, results of physicochemical analyses of water samples and dissolved gases, information on the scope of stationary studies and observations conducted at the intakes, as well as data on exploitable and available water resources, mining areas, protection zones, and documents issued by geological administration units authorizing the exploitation of these waters. In addition to data on currently classified mineral water intakes, the database also includes information on operational and research wells as well as springs where waters have been extracted or examined, which, due to their chemical composition or physical properties, may be classified as mineral resources in the future. The structure of the database is consistent with the structure of the Central Hydrogeological Data Bank (HYDRO Bank), which collects data on ordinary waters.
