Managing Geodata within the Site Selection Procedure

This contribution outlines the components of the geodata management at the Site Selection Department of the BGE, responsible for the implementation of the German site selection procedure. Its first phase is based on existing data from federal and state authorities. The BGE has implemented a comprehensive geodata management process. While incoming data and the related correspondence are stored in searchable archives, they are prepared in well-defined transfer workflows with implemented checks before usage. The data transfer from the geodata management department to the respective scientific departments includes checks for correct locations, coordinate systems, plausibility and completeness. Only standardized and officially recognized formats are used in the further analyses together with specialized software tools for GIS data, borehole data as well as geological models. The current data pool comprises 350 data deliveries from 41 institutions with approximately 1 Million data files. A significant portion of the geological data are received in analog form from the federal geological and mining authorities. Since 2 years, the BGE puts significant efforts into digitizing these data in tight cooperation with qualified geo-consultant partners. In accordance with the „Geologiedatengesetz“ (national law for usage of geological data), data relevant to the site selection procedure will be made publically available in order to fulfill obligations for public participation and the involvement of stakeholders and decision makers. The BGE strives to make data publically available as soon as the legal requirements are met and to continuously improve accessibility and user friendliness of its web-based data portal.
