Topographic Geo-Spatial Basic Data Germany
Introduction
Geo-topographic basic information in the form of digital raster data are established by the Public Surveying Authorities of the Länder and by the Bundesamt für Kartographie und Geodäsie (BKG) (Federal Agency for Cartography and Geodesy) and are covering the Topographic Map Series from 1 : 25 000 to 1 : 1 000 000 for the territory of the Federal Republic of Germany.
The relevant data covering the area of the Federal Republic of Germany are provided and distributed by the Service Centre within the Federal Agency for Cartography and Geodesy (BKG).
Raster data or Digital Topographic Maps (DTK) are data of the existing official Topographic Map Series in a raster format. They are available as different layers oriented to cartographic content (singular layers) or as a coloured combination (all layers) giving the complete map image. The maps are either
• traditional Digital Topographic Maps made as scanned analogue originals and computer-aided revision (with the mention DTK-V or “Vorläufige Ausgabe” – Preliminary edition, or
• new Digital Topographic Maps derived from a corresponding vector-based Digital Landscape Model (DLM) in the raster format showing new graphical map layout and new layer arrangement (with the mention DTK).
It is planned to give up the production of DTK-V due to the progressing setup of the Authoritative Topographic-Cartographic Information System ATKIS and the increasing availability of the DTK. For a short time of transition and in order to offer an up-to-date and largely homogeneous area-covering map series of Germany, the data derived from a DLM are produced also with the old layers and colours.
The data of the Topographic Map Series 1 : 25 000 up to 1 : 100 000 are delivered by the Länder to the Service Centre where they are harmonized, synchronized and made available. Scales from 1 : 200 000 to 1 : 1 000 000 are completely edited by BKG.
Range of raster data on offer
At present raster data of the following Topographic Map Series are offered as Digital Topographic Maps:
• Topographic Map 1 : 25 000 (DTK25-V) *)
• Topographic Map 1 : 50 000 (DTK50-V) *)
• Topographic Map 1 : 100 000 (DTK100-V) *)
• General Topographic Map 1 : 200 000 (DTK200-V)
• General Map 1 : 500 000 (DTK500-V)
• Federal Republic of Germany 1 : 1 000 000 (DTK1000)
*) Distribution of data to third parties only for areas exceeding the boundaries of a Land (state) of Germany.Federal bodies are requested to generally contact BKG.
Depending on the map series, these data are normally available for one or more resolutions between 100, 160 and 320 pixel/cm and/or between 254, 406,4 and 812,8 dpi.
As for the content the DTKs are subdivided into several singular layers (map feature levels) and oriented in principle to the map colours. Besides this they are also available as colour-coded raster image in an overall layer. Please note that some cartographic background removals have been made due to graphical reasons. For further differenciation of the content the pixels of some singular layers are coded with different (colour) values (e.g. the layers red and yellow of the DTK200-V).
For the scales between 1 : 25.000 and 1 : 200.000 there are certain differences for map graphics and colours assigned in some details between the maps in the Western and those in the Eastern Länder.
Suitability and use
Raster data of the Topographic Map Series are well suitedas spatial reference and background information when combined with expert data as well as for computer-assisted preparation and revision of thematic maps (e.g. for geology, hydrology, land use, nature preserve etc.).
Further use is possible for
• set-up of expert information systems (environment, transportation, disaster prevention etc.),
• combination with digital terrain models and/or remote sensing data,
• planning and production of 3D representations, and for
• linking with statistical data from very different appliers and users in administration and economy.
