A presentation of the new OGC API - Processes - Part 3: Workflows draft specifications, allowing to:
- chain nested processes,
- refer to external processes and collections accessible via OGC API standards, and
- trigger execution of processes through OGC API data delivery specifications (such as OGC API - Features, Tiles, Maps and Coverages).
Demonstration of use cases including crop classification, point cloud processing and routing.
Overview of the work accomplished during the GeoConnections 2020-2021 project contributing to the development of these specifications, to open standards and to free & open source software, including the development of a new unified OGC API driver in GDAL supporting the execution and visualization of results from these workflows in QGIS.
OGC API - Processes - Part 3: Workflows and Chaining is a draft OGC specification allowing to use an OGC API collection or the output of an OGC API process as an input to another process, as well as to trigger the execution of that process via data delivery requests, making the results easily accessible from OGC API clients using the data delivery APIs (e.g. Features, Coverages, Maps, Tiles...).
The latest draft specifications are available at: https://docs.ogc.org/DRAFTS/21-009.html
Financial support for the project provided by GeoConnections, a national collaborative initiative led by Natural Resources Canada.
GeoConnections supports the integration and use of the Canadian Geospatial Data Infrastructure (CGDI), an on-line resource that improves the sharing, access and use of open geospatial information.
