Concentrations measured by all monitoring networks are stored in the AQIS air pollution database. The database contains data from the beginning of measurements, and sulphur dioxide and suspended particulate matter concentrations from the station networks of the CHMI in North Bohemia and Prague from 1971. Accompanying meteorological data, which are measured at a large part of the automated monitoring stations of the CHMI are used for the evaluation of air quality-meteorological relationships, are also stored in the ISKO database. In addition, the ISKO emission database also includes data provided by cooperating institutions. These include the Public Health Institute in Ostrava, the Public Health Institute in Ústí nad Labem, the National Institute of Health, ČEZ, a. s., municipal authorities and other contributors. The database also includes information from the border areas of Slovakia, Germany, Poland and Austria.

Feature layer depicting the location of springs where the observation of yield is performed. In the past, all springs were observed by volunteers. Currently, these springs are still partly monitored in this way, and partly monitored with equipment having a daily measurement frequency. The data are stored in the Central Regime Database of Groundwater which is maintained by the Hydrology Database and Water Budget Department.

Feature layer depicting the location of boreholes observing groundwater level in shallow and deep aquifers. Currently, most of the measuring objects are equipped with automatic stations that record locally or transmit the data. These stations record once a day. Originally, the boreholes were observed by volunteers with a weekly frequency of measurement. Most of new measuring objects were built during the so-called ISPA project. They went into operation in 2007. The data are stored in the Central Regime Database of Groundwater which is maintained by the Hydrology Database and Water Budget Department.

Feature layer with the location of water-gauging stations. Over 90% of measurements are carried out through automatic stations with locally stored records or transmitted records. Discharge is derived from observed water level using rating curves, which are determined based on hydrometric measurements. The data from these stations are stored in the Central Regime Database of Surface Water which is maintained by the Hydrology Database and Water Budget Department.

This data set contains spatial data with biogeographical division of the Czech Republic. This division was elaborated initially for purposes of national and supra-national Ecological Networks. It has its own hierarchy, consisting of both individual and typological biogeographical units. Higher units (biogeographical province, subprovince, and bioregion) are of individual character. Within the territory of the Czech Republic, two biogeographical provinces, four biogeographical subprovinces and 94 biogeographical regions have been distinguished. Hierarchically lower biogeographical units (biochores, group of geobiocoene types) have typological character; their characteristics in English are intended to be published later. All of the biogeographical units - with the exception of the group of geobiocoene types - are elaborated in maps of scale 1:50 000 and are included in this data set.

For the theme Elevation INSPIRE requires data harmonisation according Elevation - Grid Coverace application schema. This dataset of the elevation of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe. Data were derived from the Digital Terrain Model of the Czech Republic – 4th generation (DMR 4G). For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and heigh reference system EVRS. Data are provided in graphic raster format (tiff) with 5 m spatial resolution together with the accompanying information in GML format.

The INSPIRE Elevation TIN data are harmonised according to INSPIRE Implementing Rules. This dataset of the elevation of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe. Data were derived from the Digital Terrain Model of the Czech Republic – 5th generation (DMR 5G). For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and heigh reference system EVRS. Data are provided in GML format, version 3.2.1. Export units are defined by tiles 2 x 2 km. The file consists mainly from coordinates of descrete points, that are supplemented by addtition information.

The INSPIRE - Geographic Names data are harmonised according to INSPIRE Implementing Rules and correspond with INSPIRE xml schema in version 4.0 and ELF xml schema in version 1.0. This dataset of geographic names of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe. The features are represented by a vector (punctual) component with attributes containing wider information about names. The base of the dataset is the database of geographic names of the Czech Republic Geonames completed with names of features located in the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®) that are not part of Geonames (street and squares names, traffic nodes and protected areas). The attributes are based on the source databases contents eventually constant on the base of characteristic of source databases (e.g. all names are Czech endonyms, names originating in Geonames standard, street names are official etc.)
