Remote sensing data management
The Remote Sensing Data Management Business Unit in SPACEBEL specializes in the development and operation of data and information acquisition, integrity, archiving, discovery, processing, retrieval, visualization, dissemination and quality control. It also encompasses the exploitation of federated and collaborative payload data ground segment services and data dissemination and all aspects related to subsystems for accessing data and information and user interface tools and methods.
Our core expertise includes Web-based Spatial Data Infrastructures and Service provisioning infrastructures facilitating interoperable discovery and access to Earth Observation data and application services consuming these data. We design, develop and maintain Web-based operational software systems, part of the ESA Payload Data Ground Segment, the Space Component Data Access of Copernicus and the Space Weather Data Center incl. the ESA/SWE Portal within the Space Situational Awareness. We also developed the EORegions! underlying exploitation-platform software which we offer to customers as a scalable cloud-based, service provisioning platform consistent with the ESA and Open Geospatial Consortium exploitation platform architecture guidelines.
More specifically, our realisations employ service-oriented or RESTful design patterns, are based on state-of-the-art interoperability standards from standardization bodies such as W3C, OASIS, ISO, OGC and rely on cloud-native (Kubernetes, Docker), Java and Web-based technology. For current implementations and activities including the ESA EO-CAT, and EO-GeoJSON standardization, we also exploit knowledge-representation, Semantic Web, Linked Data and Jupyter technology.
In addition, we provide our expertise in EO standards to standardization bodies and standardization projects initiated by the European Space Agency at a global scale in the contexts of OGC and CEOS.
Copernicus Space Component
SPACEBEL is responsible for the Interoperability Layer implementation and its maintenance. This component allows for discovery, feasibility analysis, ordering of Earth Observation products from Copernicus Contributing Missions through a single endpoint, based on orchestration and Web services technology. All interfaces implement the corresponding Open Geospatial Consortium standards. End customer: ESA
ESA Earth Observation Catalogue
EO-CAT is the Next Generation Earth Observation system designed to manage end-user Earth Observation services. SPACEBEL designed and developed the Kubernetes-based collection and product metadata catalogue and the supporting EO SKOS Thesauri. The catalogue provides access to Earth Observation products and standards-based external interfaces based on OGC EO OpenSearch and EO O&M and EO GeoJSON metadata specifications
ESA Federated Earth Observation and CEOS
ESA Federated Earth Observation missions access provides a unique entry point to a growing number of scientific catalogues and services for Earth Observation missions. It facilitates access to European missions data in the international context of the Committee on Earth Observation Satellites. SPACEBEL designed and developed the FedEO system. In addition, SPACEBEL supports ESA at the CEOS Working Group on Information Systems and Services) and is part of the System Level team. The FedEO Gateway software is also used by the German Space Agency as part of their CODE-DE environment
ESA Space Situational Awareness
SPACEBEL designed and developed the Space Weather services portal as Prime contractor for ESA. It is deployed at the SWE Data Centre in Belgium. The Portal relies on an underlying Service-Oriented Architecture and service orchestration workflows technology. An interactive Web user interface enable to retrieve data from the Space Weather Metadata Repository and access to Space Weather applications in the Data Centre
Copernicus Global Land
As part of a service contract for the EU Joint Research Centre, SPACEBEL implemented an Earth Observation Datacube, i.e. a standards-based Pixel-based access for selected Copernicus Global Land datasets. A dedicated Web client relies on an OGC Web Coverage Service interface and facilitates visual evaluation of the spatial and temporal quality of the COPERNICUS Global Land products. The DataCube allows reviewers to assess the product quality and browse the data according to its space and time axes.
SPACEBEL leads standardization activities and contributes to global open standards and publications:
- "OGC Testbed-15: Catalogue and Discovery Engineering Report"
- "OGC EO Dataset Metadata GeoJSON(-LD) Encoding Standard"
- "OGC OpenSearch-EO GeoJSON(-LD) Response Encoding Standard"
- "OGC EO Collection Metadata GeoJSON(-LD) Best Practice"
- CEOS OpenSearch Best Practice document
- "Heterogeneous Missions Accessibility" publication presents the Design Methodology, Architecture and Use of Geospatial Standards for the Ground Segment Support of Earth Observation Missions (Deliverable of HMA-Testbed project for ESA/ESRIN)
