In January, the Open Geospatial Consortium (OGC) released Part 1 of the OGC API – Processes standard. As one of the editors, I would like to provide a short introduction to the API.
WaCoDiS & CODE-DE: The future (of Earth Observation data processing) is now
Efficient Earth Observation data processing relying on CODE-DE
In April 2020, a relaunch of the Copernicus Data and Exploitation Platform – Deutschland (CODE-DE) was announced. This was a big deal, since the second generation of the CODE-DE platform should now offer public access to the long awaited online processing environment. At this time, our WaCoDiS research project was in its final term and we were ready to validate our developments as part of a pre-operational deployment. Thus, the relaunch of CODE-DE just came at the right time.
GeoNode and Kubernetes – a good match?
A closer look at the flexibility and scalability of a GeoNode deployment using Kubernetes and related Cloud concepts.
Mid-2020, we started a project with Fraym – a data science company working with manifold types of datasets to execute projects in countries that are undergoing substantial societal change places around the world where data has been traditionally hard to access. Spatial data, ranging from base data such as administrative boundaries to Earth Observation and satellite data, play an important role. The majority of the datasets will be reused in other project contexts, thus a solution for the management and discovery of spatial and non-spatial datasets is inevitable for the effective execution of data analysis processes. In close cooperation with the experts at Fraym, we developed a data platform based on the GeoNode software stack. The challenges here were a set of requirements:
- Flexibility: supporting the different dataset types such as raster, vector and tabular data
- Scalability: accommodating the large amount and variety of data (multiple terabytes, tens of thousands of more than 100k individual datasets)
- Availability: taking uptime into account (e.g. on-demand bootstrapping vs 24/7 operations)
- Processability: promoting processing functionality close to the data.
In this blogpost, we take a closer look at the first two aspects: flexibility and scalability. We look into the details of our deployment concept using Kubernetes on Amazon Web Services (AWS) and other related cloud concepts.
52°North’s Angular WPS Client Library – the wps-ng
Introduction
As we approach the end of the exciting 13 week period of the Google Summer of Code, our proposed project wps-ng has successfully fulfilled the expectations we had set forth in the beginning. With our new Client Library deployed on NPM (wps-ng), the future angular clients using this library will be able to employ standard OGC Web Processing Services along with the numerous benefits of Typescript’s static typing. We also developed a client to demonstrate the library use case and serve as a boilerplate starter for Angular projects.
