Data Management for the App UmweltNAVI of the Federal State of Lower Saxony in Germany

Joachim Müller

wemove digital solutions GmbH, Germany

The App UmweltNAVI Niedersachsen (see the poster in session "4.10" or communicates geospatial data to a broad user community of education, individuals or experts. In order to adequately present the data in a mobile context, the data must be harmonized, transformed, and combined with other sources. To achieve this, an infrastructure was created that allows editors to integrate data sources and enrich them with information. For example, Web Feature Services, ESRI Shapefiles, SensorThings APIs (STA) are under the data sources. A GUI-guided transformation process enables the mapping of raw data to the harmonized data schema. For the presentation, complex data is simplified, data reconciliation with additional data sources (i.e. Wikipedia or is performed, and the resulting data is stored in a scalable backend. Currently, the database contains 1.8 million records from 57 regional and national data sources and 178,000 images.
Only open source or freely usable software components are used, such as Elasticsearch, Postgres/PostGIS, Airflow or Directus. The delivery layer is designed redundantly for high-performance, fail-safe operation.
A standards-compliant interface (OGC-API Feautures) is being planned to provide access to the data for further processing.
The project was initiated by the Lower Saxony Ministry for the Environment, Energy and Climate Protection in Germany and was implemented together with the companies Bearingpoint and wemove digital solutions. The principle of presenting geodata can also be applied to other areas. The software is basically available for subsequent use.

The Global Heat Flow Database serves as a valuable resource for researchers studying Earth's thermal regime. However, accessing and analyzing this vast collection of geothermal data is presently challenging and limits its widespread utilization. To address this, we present a new online application to the international heat flow community, facilitating seamless discovery, access and analysis of the data. Developed within the DFG-funded World Heat Flow Database Project, it complements the evaluation of existing data and development of a new, collaborative metadata schema for heat flow data.

Our application offers an intuitive interface, allowing researchers to efficiently search, retrieve, and visualize heat flow measurements worldwide. It supports advanced search functionalities that enable users to filter data based on geographical locations, geological parameters, measurement techniques, etc. Integration of powerful data visualization tools allow users to generate maps, plots, and graphs for visual exploration and interpretation. Furthermore, the application incorporates domain relevant statistical analysis functionalities, empowering researchers to perform trend analyses and other statistical assessments directly within the platform.

Our application also aims to foster collaboration within the international heat flow community. We incorporate features such as user profiles, discussion forums, and the ability to contribute new data or review existing records. Overall, we hope to bridge the gap between heat flow specialists and valuable geothermal data by providing an innovative and inclusive platform. We believe this tool will significantly enhance scientific investigations into the Earth's thermal regime and serve as a catalyst for further breakthroughs in the understanding of geothermal processes.

Seafloor geology and the European EMODnet data infrastructure: The challenge of integrating off-shore data across EEZ boundaries

Kristine Eva Charlotte Asch

Bundesanstalt für Geowissenschaften und Rohstoffe (BGR), Germany

Within the EMODnet Geology project BGR is leading the Workpackage Seafloor geology with the aim to compile and harmonise data of the pre-Quaternary and Quaternary off-shore geology and geomorphology of the European Seas, and finally publish the results according to FAIR data principles. The data are assembled from 36 EMODnet Geology partner organisations and derived mostly from geophysical surveys (e.g. echo soundings) and sampling (e.g. drilling or dredging). Major challenges pose the heterogeneity of the provided data regarding terminology, geometry, level of detail, age of datasets and technical conditions:

  • terminology. The participating partners use their own national or regional classification systems and description;
  • geometry: artificial discrepancies at EEZ-boundaries;
  • scale: some regions are investigated in comparatively high detail while others are mapped in overview scales;
  • age: often recently mapped units need to be integrated with data resulting from earlier mapping campaigns;
  • heterogeneous technical conditions within partner organisations.

In order to ensure data interoperability and create the maps layers in a largely harmonized, unified manner, the project requires common standards e.g.

  • controlled vocabularies, optimally based on existing standards such as INSPIRE or CGI-GeoSciML terminology,
  • a straightforward data model and
  • a pragmatic approach that takes into account the realities of the project partners.

This presentation will demonstrate the methodological approach to collate and combine data, information and knowledge from over 30 international partners and the challenge to develop, integrate and publish largely harmonized map layers of the off-shore geology of Europe and beyond.

Description of scientific metadata at the Federal Waterways Engineering and Research Institute (BAW)

Vikram Notay

Federal Waterways Engineering and Research Institute (BAW), Germany

The Federal Waterways Engineering and Research Institute acts as a consultant for and supports the Federal Ministry of Digital and Transport (BMDV) and the Federal Waterways and Shipping Administration (WSV) in navigation-related water engineering tasks. It creates and uses large volumes of scientific data like digital elevation models, simulation results, monitoring data, etc. as part of these activities. The description of this data with metadata is an essential prerequisite for its long-term storage, publication, retrieval and reuse. The requirements for metadata management were implemented with the INGRID software. INGRID offers various interfaces for capturing and processing metadata. It behaves format-agnostic, so different metadata formats can be processed.

The requirements for metadata processing at BAW are quite extensive and differ from the possibilities of usual geodata portals. As a result, custom fields and data classes have been defined in the metadata model. The ISO19139 metadata is used for transferring metadata to external geodata portals. A DOI data record can be generated from the metadata, which can in perspective also be registered automatically at To ensure the description of simulation results with metadata, the delivery of metadata together with data is firmly established in the workflows for data archival and publication.

The presentation describes the requirements for metadata processing, the basic structure of the application, and discusses the life cycle of metadata.
