Digital administrative boundaries NW (low base density)

For the entire state area of North Rhine-Westphalia, DLM derived administrative boundaries (closed polygons) are available as vector and grid data in two levels of detail. In addition to the circumferential geometry, the data also includes the names and identifiers of the administrative units. The digital administrative boundaries are available throughout North Rhine-Westphalia. DVG2: Reduction to approximately 10 % of the points of the DVG1 (administrative limits with all limit points from the ATKIS® base DLM, thinning and Douglas-Peucker algorithm)

针对北莱茵-威斯特伐利亚州（North Rhine-Westphalia）全域范围，数字景观模型（Digital Landscape Model, DLM）衍生的行政边界（闭合多边形）以矢量与栅格数据形式提供，包含两种细节层级。
除周界几何信息外，该数据集还包含行政单元的名称与标识符。
这套数字行政边界数据覆盖北莱茵-威斯特伐利亚州全域。
DVG2：将点数精简至约为DVG1的10%；其中DVG1为源自ATKIS®基础DLM的包含全部边界点的行政界线，通过道格拉斯-普克（Douglas-Peucker）算法完成抽稀处理。
