INSPIRE: Information system salt structures: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air) (InSpEE)

InSpEE (INSPIRE) provides information about the areal distribution of salt structures (salt domes and salt pillows) in Northern Germany. Contours of the Salt Structures can be displayed at horizontal cross-sections at four different depths up to a maximum depth of 2 000 m below NN. The geodata have resulted from a BMWi-funded research project “InSpEE” running from the year 2012 to 2015. The acronym stands for "Information system salt structures: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air). Additionally, four horizontal cross-section maps display the stratigraphical situation at a given depth. In concurrence of maps at different depths areal bedding conditions can be determined, e.g. to generally assess and interpret the spread of different stratigraphic units. Clearly visible are extent and shape of the salt structures within their regional context at the different depths, with extent and boundary of the salt structures having been the main focus of the project. Four horizontal cross-section maps covering the whole onshore area of Northern Germany have been developed at a scale of 1:500.000. The maps cover the depths of -500, -1000, -1500, -2 000 m below NN. The four depths are based on typical depth requirements of existing salt caverns in Northern Germany, mainly related to hydrocarbon storage. The Shapes of the Structures Show Rudimentary Information of their geometry and their change with depths. In addition they form the starting point for rock mechanical calculations necessary for the planning and construction of salt caverns for storage as well as for assessing storage potentials. The maps can be used as a pre-selection tool for subsurface uses. It can also be used to assess coverage and extension of salt structures. Offshore areas were not treated within the project. All horizontal cross-section maps were adjusted with the respective state geological survey organisations. According to the Data Specification on Geology (D2.8.II.4_v3.0) the content of InSpEE (INSPIRE) is stored in 15 INSPIRE-compliant GML files: InSpEE_GeologicUnit_Salt_structure_types.gml contains the salt structure types (salt domes and salt pillows), InSpEE_GeologicUnit_Salt_pillow_remnants.gml comprises the salt pillow remnants, InSpEE_GeologicUnit_Structure_building_salinar.gml represents the structural salinar(s), the four files InSpEE_Structural_outlines_500.gml, InSpEE_Structural_outlines_1000.gml, InSpEE_Structural_outlines_1500.gml and InSpEE_Structural_outlines_2000.gml represent the structural outlines in the corresponding horizontal cross-sections, the four files InSpEE_GeologicUnit_Cross_Section_500, InSpEE_GeologicUnit_Cross_Section_1000, InSpEE_GeologicUnit_Cross_Section_1500 and InSpEE_GeologicUnit_Cross_Section_2000 display the stratigraphical situation in the corresponding horizontal cross-sections and the four files InSpEE_GeologicStructure_500.gml, InSpEE_GeologicStructure_1000.gml, InSpEE_GeologicStructure_1500.gml and InSpEE_GeologicStructure_2000.gml include the relevant fault traces in the corresponding horizontal cross-sections. The GML files together with a Readme.txt file are provided in ZIP format (InSpEE-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.InSpEE（INSPIRE）数据集提供德国北部盐构造（盐丘与盐枕）的面状分布信息。该数据集可展示以德国正常海平面（NN）为基准、最大埋深达2000米的四个不同深度的水平剖面盐构造等值线。本套地理数据源自2012至2015年间由德国联邦经济事务与气候保护部（BMWi）资助的“InSpEE”研究项目。其缩写全称意为“盐构造信息系统：可再生能源（氢能与压缩空气）储存盐穴建设的规划依据、遴选标准与潜力评估”。 此外，四张水平剖面地图可展示特定深度的地层情况。通过不同深度的剖面，可确定区域层理条件，例如用于总体评估和解译不同地层单元的展布范围。在各深度的区域背景下，盐构造的范围与形态清晰可见，而盐构造的分布范围与边界正是本项目的核心研究重点。 研究团队制作了四张比例尺为1:500000的地图，覆盖德国北部全陆上区域，对应埋深分别为NN基准下的-500、-1000、-1500、-2000米。这四个深度参考了德国北部现有盐穴（主要用于油气储存）的典型埋深需求。 盐构造的形态展现了其几何形态及随深度变化的基础信息，同时也是盐穴储存规划与建设所需岩石力学计算的起点，亦可用于评估储存潜力。本数据集可作为地下利用的预选工具，还可用于评估盐构造的覆盖范围与延展规模。本项目未涉及近海区域。 所有水平剖面地图均已与对应州级地质调查机构完成校准。根据《地质数据规范（Data Specification on Geology, D2.8.II.4_v3.0）》，InSpEE（INSPIRE）数据集以15份符合INSPIRE标准的地理标记语言（Geography Markup Language，GML）文件存储： 1.
