Digital Topographic Map 1 : 1 DTK 2 Description of data contents 2.1 General The Digital Topographic Map 1 : 1 (DTK) includes the raster data of the General Map Deutschland 1 : 1 (D) (normal edition). The raster data are subdivided into several layers according to their cartographic content. The DTK has one combined layer as well as six single and six additional layers. The combined layer (layer ) is a combination of the single layers 1-4, 6 and 7 and offers the complete coloured map image of the D. The additional layers (layers 5, 8-9) contain further information on vegetation, hill shading, and hypsometric tints and also provide the geographical and UTM grids (layers 1, 11). These additional layers have to be ordered explicitly since they are not part of the standard supply for single layers. Colours and structure of single and additional layers for the DTK basically correspond to the colours of the D. For practical reasons, some layers received additional thematic attributions of individual map elements. This implies an advantage for the user since each layer covers the whole federal territory. The single layers of all Digital Topographic Maps distributed by the BKG have an identical structure, except for some scale-dependent special characteristics. More differentiated information is allowed by colour channels which are part of the single and additional layers. Certain cartographic elements are assigned to these channels (see chapter 2.2). Please note that cartographic symbols may contain graphical gaps to avoid certain overlays with symbols of other layers. This is because the single layers were generated for the purpose of map printing. 2.2 Content and colour charts of the single and additional layers The following tables give descriptions of the content and the colour chart of each layer. The headline indicates the following: - Number of layer, e.g. Layer 1 - the essential content (the essential print colour in brackets) and - Priority, e.g. P6, indicates in which order the single layers have to be combined to produce the combined layer.

Digital Topographic Map 1 : 1 DTK 3 Information on data supply It is possible to select from different thematic sets of layers and georeferencing systems. The area of interest can be defined in any form and size, preferably rectangular. For large areas it is necessary to split the delivery into seamless tiles (see chapter 5). The Service Centre of the Federal Government for Geo-Information and Geodesy (Dienstleistungszentrum, DLZ) (www.geodatenzentrum.de) offers all possibilities of data supply, guides the user through the product line and indicates standard specifications and special services as well as the pricing system (see chapter 9). The information of the last update is indicated in the meta information: www.geodatenzentrum.de > About data and services > Overviews actuality The map sheet, each map tile and each rectangular section is supplied with an.akt-file showing the map sheets name and the year the map sheet has been updated. Example: Content of the file s3_4_1.akt DTK;217 4 Map sheet and BKG tiling systems The single map sheet is offered in the sheet line system of the General Topographic Map 1 : 1 (D), i.e. one raster data file is produced for each layer of this map sheet. To provide large amounts of seamless data we use the long-term defined tiling scheme by BKG. Dependent on the georeference the data will be split into square tiles. This supports the user in processing the current data more efficient and in updating the data by replacing single tiles. Sheet and tile indexes are available at www.geodatenzentrum.de Information and notes. The DTK is provided as a set of 8 km x 8 km tiles. The tiles are numbered by rows and columns, beginning top left with _. For example the tile s3_6_8 covers the 7 th row and 9 th column of the tiling system in the 3 rd meridian strip of the Gauss-Krüger projection. DTK page 19
Digital Topographic Map 1 : 1 DTK 5 Description of data formats The data will be delivered on the selected data carrier and will have the following directory structure: <Name of the product> <Name of the map sheet, the tile or the region> <Name of the layer >.tif <Name of the layer >.tfw... <Name of the map sheet, the tile or the region>.akt Example tiling scheme: dtk-v s3_3_4 s3_3_5 l1.tif l1.tfw l2.tif l2.tfw l7.tif l7.tfw s3_3_4.akt l1.tif l1.tfw l2.tif l2.tfw The following georeferencing information is available for each raster index: - corresponding World file (file extension.tfw ) - embedded georeferencing information (GeoTIFF). Colour coded data (the combined layer and the single layers as standard) will preferably be delivered as packed LZW. The TIFF format uses an integrated RGB palette. Colour depth is 8 bit by default.
