ATKIS — Digital Basic Landscape Model — 2939-NO Dahlhausen

The Digital Basic Landscape Model (ATKIS Base DLM) is a digital, object-structured vector dataset. It determines the topographical objects of the real world by location and shape, names and characteristics. Furthermore, object-related material data are linked in such a way that the database can be used in a GIS application. In order to achieve a nationwide content uniformity of the data, the basic DLM is defined by means of an object type catalog derived from the AAA application scheme (ATKIS-OK Basic DLM), which contains regulations on the content and modelling of topographic information for the AdV basic data base and the country solutions. In addition to the objects of the object category groups ‘Siedlung’, ‘Transport’, ‘Vegetation’, ‘Waters’, ‘Administrative territorial units’ and ‘Relief Forms’, the contents also include structures and facilities on settlement areas and for traffic, as well as specific information on the waters. The position accuracy for the main linear objects (road axes, road axes, railway lines and water axes) is ± 3 m. When using a database, the ATKIS data can be submitted either completely or as user-related inventory data update (NBA) according to the customer’s desired time cycles. The data is provided free of charge via automated procedures or by self-collection. When using the data, the license conditions must be observed.数字基础景观模型（ATKIS Base DLM）是一款面向对象的数字化矢量数据集。其通过空间位置、几何形态、名称及属性特征，对现实世界中的地形对象进行定义。此外，与对象绑定的属性数据已完成适配关联，可直接在地理信息系统（Geographic Information System, GIS）应用中调用该数据库。为实现全国范围内的数据内容一致性，基础DLM通过源自AAA应用架构（ATKIS-OK 基础DLM）的对象类型目录进行规范定义，该目录针对AdV基础数据库及各国本地化方案，明确了地形信息的内容标准与建模规则。除“居住聚落”“交通设施”“植被”“水域”“行政辖区”与“地貌形态”六大对象类别组外，该数据集还涵盖聚居区内与交通领域的建构筑物及配套设施，以及水域专项信息。主要线性对象（道路轴线、道路轴线、铁路线路及水域轴线）的平面定位精度为±3米。在数据库使用环节，ATKIS数据可根据客户期望的更新周期，以全量数据集或用户专属存量数据更新包（NBA）的形式交付。该数据可通过自动化流程或自助申领的方式免费提供。使用该数据时，需严格遵守相关许可协议条款。
