Customer: Centre National d’Études Spatiales (CNES)
Programme: SWOT aval
Supply Chain: CNES > CS Group SPACE
Context
CS Group responsabilities for Development of a centralized portal for hydrological data are as follows:
- Design, development and deployment on CNES and Cloud means.
- Guarantee and maintenance.
- Support and training for users, community animation.
The features are as follows:
- HYGOR: ManaGement and ORorganization of data
HYDROWEB-NG: Dissemination of data
HYMOTEP: Production of data
STYX (Science Testbedand hYsopeII data eXploration): Scientific exploration
HYDRA (Detection, Report and Analysis): Hypervision of the system
Project implementation
The project objectives are as follows:
- A system for centralization, provision and processing of hydrological data, to better understand the water cycle
- For scientific, institutional, private or educational accesses
- Brings together all useful data (spatial, in situ, model, etc.)
- Single French access to SWOT HR data, a major revolution in the quantity of hydrological measurements
The processes for carrying out the project are:
- The HYSOPEII system is developed in Agile/DevOps mode and uses the UXDesign method to collect user needs.
Technical characteristics
The solution key points are as follows:
- Reuse of CNES components: REGARDS (cataloging); CHRONOS (orchestrator); VRE (scientific exploration)
- Free standards and components
Portability and scalability: Stateless microservices; Docker and Singularity; Kubernetes; Ansible and Helm; Portable on CNES and CLOUD infrastructure
- User-centered design
