WFS services

Web Feature Services (WFS) is a standard protocol for downloading geospatial vector datasets to the Internet and is generated by a map server using data from a GIS database.

The author of the WFS specification is the Open Geospatial Consortium (OGC). The latest version of WFS is 2.0, released on November 2, 2010. More information on WFS is available from the OpenGeospatial Consortiumweb page.

The Latvian Geospatial Information Agency WFS is a direct connection to the database. When downloading, the user can specify an area that requires vector data.

Data is downloaded from the server to the OGC standard GML (Geography Markup Language) format.

WFS services are supported by GIS software ArcGIS from version 9.3, and QGIS from version v1.6, as well as MapInfo and GeoMedia software.
