HOWTO pygeoapi

The pygeoapi config is the place to start when configuring a new service. The file starts with some general server configuration and then presents a list of collections. Each collection has a data store configuration referencing one of the available data backends. A common data provider is the OGR/GDAL provider which gives access to a multitude of file formats.

In a minimal approach you can update the current config file and add a new layer to it.

Alternatively you can create a new instance by duplicating the main pygeoapi service folder under a new name and update the main ansible orchestration to add the new service. Also you have to create a new file in https://github.com/Geonovum/ogc-api-testbed/tree/main/.github/workflows, having the new name. This tells github to (re)deploy the service when changes are detected. Note that INSPIRE mandates that each dataset is exposed via a unique service endpoint and pygeoapi can only provide a single service endpoint. Duplicating the deployment is then a usual approach.

Example of a pygeoapi collection

lakes:                                                      # name of the collection, e.g. /collection/lakes/items
        type: collection 
        title:                                              # title, keywords and description support multilingual
            en: Large Lakes
