Web Map Service (WMS) is an international standard for dynamic spatial data sharing via Internet where data are published in the form of digital image files. The list of standards is available on the website of Open Geospatial Consortium (OGC): http://www.opengeospatial.org/standards/wms.

Detailed information on the sharing of spatial data in accordance with the standards of INSPIRE can be found at: http://inspire.jrc.ec.europa.eu/index.cfm/pageid/5.

Geoportal provides the following services:

Geoportal integrates services provided by communes and districts WMS servers (NSDI) as well as other external servers.

There is suitable tool that allows user to connect to WMS server and then display the map. The most popular map data formats used to render the image are GIF, JPEG and PNG.


All services provided by communes and counties must be based on appropriate and universal schema. Symbolization rules are determined to make layers data readable in particular on the white background, black and white orthophotomap ( Geoportal's basemap) or coloured orthophotomap background.


Detailed rules of creation of WMS Services with cadastral data are defined in the document: "Dystrybucja geometrycznych danych wielkoskalowych oparta o serwery WMS i WFS".
