Drilling archive

This is a georeferenced data collection (database) with the released geoscientific drilling and profile data from the geological strata directories. The basis of data encryption is the “symbol key geology (SEP1 of 1991)” of the Staatlich Geological Services of Germany. The data will be presented in the Hamburg drilling data portal, if a release is available for publication. For free machine processing in accordance with the Hamburg Transparency Act, data in the format gml is provided in a rar archive. This contains the master data of all holes. Due to its size, the layer data is divided into 7 files according to the districts of Hamburg and, for data protection reasons, does not contain the data of private drilling for which there is no release for publication. The download files are updated as required. For a better understanding of the data, a file with field descriptions and key lists is also provided. The data will also be provided by WFS BoreholeML 3.0 Header and ¶WFS BoreholeML 3.0 Header and ¶WFS BoreholeML 3.0 for the drill point map Germany, if released for publication. The data are not available here in the original SEP1 but in the undifferentiated BoreholeML3 format. These two services provide complex GML schemas that cannot be easily processed by standard GIS clients such as ArcMap or QGis.本数据集为经地理空间参考的数据集合（数据库），收录了来自地质地层目录的已公开地球科学钻探与剖面数据。 本数据的加密依据为德国国家地质服务机构制定的《符号密钥地质学（1991年SEP1版）》。 若满足公开发布条件，该数据将在汉堡钻探数据门户网站上线展示。 为遵循《汉堡透明度法案》实现免费机器处理，本数据集以GML（Geography Markup Language，地理标记语言）格式打包于RAR压缩归档中提供。 该归档包含所有钻探孔位的主数据。 由于图层数据体量较大，其按照汉堡行政区划分拆为7个文件；同时出于数据保护考量，未包含未获准公开的私人钻探数据。 下载文件将按需进行更新。 为便于使用者理解数据内容，本数据集还附带一份包含字段说明与密钥列表的辅助文件。 若获准公开发布，面向德国钻探点位地图的WFS（Web Feature Service，网络要素服务）BoreholeML 3.0及其头部接口也将提供本数据的访问服务。 本数据集未采用原始SEP1格式提供，而是采用未分化的BoreholeML 3格式进行交付。 上述两类接口所采用的GML架构较为复杂，无法通过ArcMap、QGIS等标准GIS客户端直接进行处理。
