Data download application

Geoviewer
The application offers the following options for downloading file data via the links listed in the product metadata ("Product Information" table, "Distribution" and "Data Download" sections), or directly in the Geoviewer ("Layer List" tab, "Options" menu):

• download data, i.e. pre-prepared files provided by ATOM services. The data is divided into suitable dispensing units and stored in at least one of the open formats. The number of dispensing units to download is determined by the extent of the map window. The Maximum number of 100 searched units is determined by the limitation of the OpenSearch service, which provides searches over datasets.
• export data to various formats in the form of seamless sections determined by the extent of the map window, boundaries of administrative units, parcels or using a custom vector polygon. Space limitations for data export are listed for each product in this overview.

Furthermore, the Geoviewer allows downloading vector objects from connected ArcGIS REST map services. After marking the object in the map, it is offered to download it in GeoJSON format.

Atom download services
The application provides an overview of all open data of the ČÚZK resort. Allows selection and download of pre-made files provided by ATOM services. The number of dispensing units to download is determined by the extent of the map window. The Maximum number of 100 searched units is determined by the limitation of the OpenSearch service, which provides searches over datasets.

Application for submitting a request for the provision of another form of open data.

Based on the request of the registered user, the Eshop application provides, in addition to paid aerial survey images, archives and printed products, also data from ZABAGED®, orthophoto of the Czech Republic, state maps series and database of geographic names, which are classified as open data.

The user has the option to submit a request for data in other forms in this application (or by e-mail at the address zu.praha@cuzk.cz), i.e.

• choose a data file format different from the one in which the data is recorded in the national open data catalog, i.e. different from the vector or raster formats provided by ATOM download services, or WFS or WCS.
• choose a place to download data using remote access and transfer it to a technical data carrier.

In addition, it is possible to indicate other data editing requirements in the "Note" section when compiling the application (for example, preparation of a format that is not on the menu of the Eshop or the Geoviewer export tool, or the storage of files in a specific delivery unit).
 
The formats and dispensing units that we offer as standard are listed in this overview.
 
The payment for conversion to the required format (or for other data modifications) is paid according to the hourly rate specified in point 11 of the annex to Decree No. 31/1995 Coll., which implements Act No. 200/1994 Coll., on surveying and on amendments and additions of some laws related to its introduction as amended.

Notes: We recommend submitting a request for the transfer of data on a technical data carrier via the Eshop application in order to obtain one-time large volumes of data if necessary. In particular, this concerns data from the orthophoto of the Czech Republic, a height chart or state maps series  from a large area (e.g. the entire region).
 
Directly downloading open data from the data store using the above applications and services may not be effective in this case, due to the load on the transmission lines, and is not primarily intended for these cases.
In the case of excessively long downloads or other problems or ambiguities regarding the provision of data, please contact the Department of Distribution and Support of the Land Surveying Office at zu.praha@cuzk.cz.
