New data describing Prague and life in the metropolis are constantly being created.
On the geoportal you will find a range of open data that you can use for scientific or even commercial purposes, completely free of charge. Cities know that open data brings positive results.
Open Data is information and data available freely and free of charge on the Internet in a machine-readable format. There are no legislative or technical barriers to their use. At the same time, the publisher grants permission for further processing and the data can be freely used for research, analysis and commercial purposes, for example for the creation of web applications.
For publishing vector open data, we use partly the ArcGIS Hub platform, which allows you to download data in several formats, connect to the data via API, or many other functionalities that make working with data easier.
Raster data and specific 3D data are provided as pre-packaged downloads.
How to get the data
Vector data in WGS84 are provided on ArcGIS Hub.
Data in S-JTSK are prepared as files to download.
We provide vector data in WGS84 on the ArcGIS Hub platform, where you simply select the area of interest on the map. Vector data in S-JTSK, raster data and 3D data are available as a package for the whole of Prague or can be downloaded by map sheets.
Open data is provided in multiple formats to make it as widely used as possible. Vector formats are designed for specialized software that can work with geographic data.
Vector formats ArcGIS Hub (WGS84):
- SQLite geodatabase, Feature geodatabase, GeoPackage, geoJSON, KML - formats for developers and GIS specialists
Vector formats (S-JTSK):
- SHP - format for GIS software
- DXF - format for CAD software
Raster formats (S-JTSK):
- TIFF, JPEG
3D formats:
