Area codes, local network names and geographical borders between local networks
Local network codes (area codes), their assignment to local network names, and the geographical boundaries between local networks are defined in Annex 1, while the geographical borders between local networks are specified in Annex 2 to the KEM-V 2009.
The borders between local networks can be downloaded below in the form of a Google Earth-compatible file "Ortsnetze KEM-V.kml" (zipped as "Ortsnetze KEM-V 2009.kml.zip"). The geographical borders between local networks have also been drawn as polygonal chains using the ArcView geographical information system. The background map used is the digital raster map of Austria based on TELE ATLAS data as of 2002 and the polygonal chain depicting the borders between Austrian municipalities (ArcData No.: AA-GEM-2001) as of October 23, 2003, supplied by WIGeoGIS GmbH. The borders between local network areas are therefore also available in the ArcView-compatible file "Ortsnetze KEM-V 2009.ARC-View.zip"; the names of the local networks can be downloaded in the file "Ortsnetznamen.xls".
Although the data is available in a format compatible with Google Earth and ArcView, the data published in the Federal Law Gazette represents the only legally binding definition.
