INSPIRE: Map of Near-Surface Deposits of the Federal Republic of Germany 1:250,000 (KOR250)
收藏资源简介：
The KOR250 (INSPIRE) in the scale of 1:250,000 shows occurrences and deposits of mineral resources in Germany, which lie close to the Earth’s surface, i.e. can be mined in open-pits, quarries or near-surface mines. These mineral resources include Industrial Minerals, aggregates, peat, lignite, oil shales, and natural brines. The map is derived from the KOR250, the digital successor of the map series KOR200 “Map of Near-Surface Deposits of the Federal Republic of Germany 1:200,000”, which has been published since 1984. The KOR200 and KOR250 have been published by the Federal Institute for Geosciences and Natural Resources together with the State Geological Surveys of the federal states on behalf of the Federal Ministry for Economic Affairs and Energy. Primary purpose of the KOR250 is to display Germany’s potential of domestic raw materials in a comparable way. The explanations given in the printed booklets accompanying the KOR200 are not available in the digital KOR250. In the KOR250 besides the defined deposits and differently coloured areas of raw materials, “active mines” (= operations) at time of publication or “focal points of several active mines” are marked with one symbol each. These mines are not included in the KOR250 (INSPIRE) as often the headquarters of the mining company and not the mining site itself is displayed as well as in many regions the dataset is outdated. As the map sheets of the KOR200 have been generated over more than three decades the timeliness of data is extremely different. For more detail, the current large-scale raw material maps of the Federal State Geological Surveys should always be consulted. The point data displayed in KOR250 (INSPIRE) indicate very small, but worth mentioning prospects of certain raw materials. According to the Data Specification on Mineral Resources (D2.8.III.21) the content of the map is stored in two INSPIRE-compliant GML files: KOR250_EarthResource_polygon.gml comprises the mineral resources as polygons. KOR250_EarthResource_point.gml comprises the mineral resources as points. The GML files together with a Readme.txt file are provided in ZIP format (KOR250-INSPIRE.zip). The Readme.text file (English/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements. Notes: It should be noted that according to the INSPIRE commodity code list, most magmatites and metamorphites were assigned to the two values “granite” and “basalt”. From a geological point of view and with regard to its origin, this assignment is often misleading. For more information on the outcropping rock of a specific raw material occurrence, the German name from the original KOR250 was mapped to the attribute name of the class GeologicFeature.

1:250 000比例尺的KOR250（欧洲空间信息基础设施（Infrastructure for Spatial Information in the European Community, INSPIRE）兼容数据集）展示了德国境内接近地表、可通过露天矿、采石场或近地表矿井开采的矿产资源产出点与矿床。此类矿产资源涵盖工业矿物、建筑集料、泥炭、褐煤、油页岩与天然卤水。 该数据集源自KOR250，是自1984年起发布的KOR200系列地图《德意志联邦共和国1:200 000近地表矿床图》的数字化后续版本。KOR200与KOR250由德国联邦地球科学与自然资源研究所（Federal Institute for Geosciences and Natural Resources, BGR）会同联邦各州地质调查局，受联邦经济事务与能源部（Federal Ministry for Economic Affairs and Energy）委托发布。 KOR250的核心用途是以标准化可比的方式展示德国国内的原材料资源潜力。KOR200配套印刷手册中的说明文档并未在数字化的KOR250中提供。 在KOR250中，除已划定的矿床与不同着色的原材料分布区域外，发布时处于运营状态的"在产矿井"（即实际开采作业）或"多个在产矿井的集中区域"均会以专属符号标注。但此类矿井并未纳入KOR250（INSPIRE）数据集，原因在于多数情况下标注的是矿业公司总部而非实际采矿场地，且在诸多区域该数据集已过时。 由于KOR200的图幅耗时三十余年完成编制，其数据现势性差异极大。如需获取更详细的信息，应始终参考联邦各州地质调查局发布的最新大比例尺原材料地图。 KOR250（INSPIRE）中展示的点数据，指代规模极小但仍具有提及价值的特定原材料勘探远景。 根据《矿产资源数据规范（Data Specification on Mineral Resources, D2.8.III.21）》，该数据集内容存储于两个符合INSPIRE标准的地理标记语言（Geography Markup Language, GML）文件中： 1. KOR250_EarthResource_polygon.gml：以多边形要素形式存储矿产资源数据； 2. KOR250_EarthResource_point.gml：以点要素形式存储矿产资源数据。 上述GML文件与Readme.txt文件打包为ZIP压缩包（KOR250-INSPIRE.zip）。该Readme.txt文件（英文版本）包含了关于GML文件内容的详细说明。数据转换工作依据INSPIRE相关要求，借助FME（Feature Manipulation Engine）的INSPIRE解决方案包完成。 备注： 需注意，根据INSPIRE商品编码列表，多数火成岩与变质岩被归类为"花岗岩"与"玄武岩"两类。从地质学视角及其成因来看，此种归类往往存在误导性。如需获取特定原材料产出点的出露岩石详细信息，可将原始KOR250中的德语名称映射至地理要素类（GeologicFeature）的属性名称中。 KOR200相关链接：https://www.bgr.bund.de/EN/Themen/Min_rohstoffe/Projekte/Rohstoffverfuegbarkeit_laufend_en/KOR_200_en.html
