Ingesting new datasets in the ESA PRR

The ESA Project Results Repository (PRR) is an ESA managed and curated data repository for higher level value-added products (e.g. L3/L4) typically created within projects initiated by the EOP-S department (Climate Action, Sustainability and Science Department). The repository is publicly accessible and catalogued using STAC.

  • The interoperability guidelines and requirements for EO projects and data providers who wish to deliver their datasets within the PRR for long-term preservation and further downstream utilisation are provided here. 

  • For dataset visualization on the APEx Geospatial Explorer, ensure the datasets meet the additional compliance requirements outlined in the next section Visualizing data on the APEx Geospatial Explorer. 

Additional Resources

  • The ESA PRR Frequently Asked Questions section offers additional details on datasets contribution and integration procedures.

  • The reg-api-client includes a client application utilized to ingest data; accompanying metadata shall follow a specified profile and can be created and validated using this editor. 

  • The EarthCODE project provides practical tutorials on how to generate STAC-compliant data collections directly from files and to data ingestion operations.

 

 

 

Visualizing data on the APEx Geospatial Explorer

ESA's Application Propagation Environments (APEx) initiative provides easy access to ESA's Earth observation application outcomes for the EO community, with a range of services and tools to build upon EO projects and sharing results.

The Geospatial Explorer (GE) provides an interactive web front end that can be used for the display and visualisation of geospatial and tabular data ingested in the PRR or fetched from web services following common interoperable protocols (e.g. OGC Standards, STAC).

  • To support the smooth integration of datasets in the GE, it is essential that all datasets adhere to the general file format recommendations. Following these guidelines ensures compatibility and ease of integration within the APEx GE.

  • When referencing data through a STAC catalogue, it is further advised to comply with the STAC metadata recommendations. Adhering to these metadata standards will improve dataset discoverability, interoperability, and enable seamless integration with the GE.

Additional Resources

Typical GE functions include the ability to visualize EO data, derived products and associated vector layers with control over layer ordering, transparency, product comparisons and support for features such as cursor inspection, queries, distance measurements and visualization of tabular data via integrated charts and graphs.

  • This is a demo of the GE features.

  • The GE application is configured through a hosted JSON object with the following structure and properties options.

  • The GE Configuration Builder utility can be used to create JSON configurations and this workshop covers how to create new configuration from scratch, showing how to connect to various data sources (e.g. COG, FlatGeobuf) and services (WMS / WMTS / STAC).
