Pre-use in the greater Saarbrücken area

Presentation of the pre-use for 12 DGK 5 sheets in the greater Saarbrücken area. On the basis of the original geometry of the “current land use”, all areas that were classified as unbuilt during the last processing were presented transparently and backed up with the current orthophotos. This has allowed to identify overbuilt surfaces on the screen and encode them accordingly in a newly generated field (“VOR_NUTZ”). Attribute fields: “VOR_NUTZ” = coding of the usage type according to the key of the AG Stadtbiotop mapping (1993), Verbalised designation in the text document “nutztyp.doc”.萨尔布吕肯大都市区内12幅DGK 5图幅的预用地现状展示。本数据集以“当前土地利用”的原始几何要素为基础，将上次处理流程中被归类为未建设状态的区域以透明叠加形式呈现，并辅以当前正射影像（orthophotos）作为佐证。借此可在屏幕端识别出超占建设区域，并在新生成的“VOR_NUTZ”字段中完成对应编码。属性字段说明如下：“VOR_NUTZ”为依据1993年城市生境工作组（AG Stadtbiotop）制图规范编码的用地类型，其文字化命名详见文本文件“nutztyp.doc”。
