OGC Testbed Experiments¶

Images and Changesets¶

A couple of extra API, images and changesets, based on engineering reports of Testbed 15, allowing to update a image mosaic and get a list of tiles affected by the change.

To install these modules:

1. Download the OGC API nightly GeoServer community module from geoserver-2.27.x-ogcapi-images-plugin.zip.

   Warning

   Verify that the version number in the filename corresponds to the version of GeoServer you are running (for example geoserver-2.27-SNAPSHOT-ogcapi-images-plugin.zip above).

2. Extract the contents of the archive into the WEB-INF/lib directory of the GeoServer installation.

3. On restart the services are listed at http://localhost:8080/geoserver

DGGS¶

The DGGS functionality exposes data structured as DGGS, based on either H2 or rHealPix, based on engineering reports of Testbed 18.

To make full usage of the DGGS functionality, a ClickHouse installation is also needed.

To install these modules:

1. Download the OGC API nightly GeoServer community module from geoserver-2.27.x-ogcapi-dggs-plugin.zip.

   Warning

   Verify that the version number in the filename corresponds to the version of GeoServer you are running (for example geoserver-2.27-SNAPSHOT-ogcapi-dggs-plugin.zip above).

2. Extract the contents of the archive into the WEB-INF/lib directory of the GeoServer installation.

3. On restart the services are listed at http://localhost:8080/geoserver

The DGGS datastore can read data from a ClickHouse database. In case you want to use JNDI along with Tomcat, here is a sample data source declaration for the etc/context.xml file:

<Resource name="jdbc/clickhouse" auth="Container" type="javax.sql.DataSource"
            maxTotal="100" maxIdle="30" maxWaitMillis="10000"
            username="myUser" password="myPassword" driverClassName="ru.yandex.clickhouse.ClickHouseDriver"
            url="jdbc:clickhouse://localhost:8123/theDatabase?http_connection_provider=HTTP_CLIENT"/>
