Circle

The data set contains the polygons of the 44 city and districts of Baden-Württemberg. The geometry data of the circle boundary 1:2,000 (data source: Surveying on site) originates from the ALKIS theme “Kreis” of the “User Oriented Geobase Data Baden-Württemberg (NORA_BW)” and is linked to the factual attributes of the State Statistical Office Baden-Württemberg after a geometric validation in the UIS. Analog with the circle boundary 1:10.000 (data source: Capture from the Digital Orthophoto). The geometry data used for this purpose are derived from the basic DLM theme “circle” from NORA_BW. This data set is also validated geometrically and enriched with regard to the factual data. In addition, in the area of Lake Constance, the shoreline of the AWGN specialist objects “Bodensee – Obersee” and “Bodensee – Untersee” is used as a border line.
