The Digital Landscape Model 1:250 000 (DLM250) describes the topographic features of the landscape in the vector format. The features are assigned to a certain feature type and defined by their spatial position, their geometric type and describing attributes. The ATKIS feature type catalog (ATKIS-OK) defines which feature types are contained in the DLM and how the features have to be formed.
The data are cartographically generalized according to the signature catalog (SK250) of the Digital Topographic Map 1:250 000 (DTK250). But they have a better position accuracy (± 100m) for the most important point and line objects.
The DLM250 is part of the Authorative Topographic-Cartographic Information System (ATKIS®) and is based on the common data model for AFIS®, ALKIS® and ATKIS®.
Especially, each user has to place the source reference to all geodata, metadata and geodata services recognisably and optically linked. Alterations, processings, new designs or other adaptations have to be affixed with an indication of the alteration in the source reference.
Source reference and indication of alteration have to be formulated as follows. The source reference has to be linked with the URL "http://www.bkg.bund.de" for the representation at a website.
