OGC Testbed Experiments

The following module is part of the OGC Testbed experiments.

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. Login, and navigate to About & Status > About GeoServer and check Build Information to determine the exact version of GeoServer you are running.

  2. Visit the website download page, change the Development tab, and locate the nightly release that corresponds to the GeoServer you are running.

    Follow the Community Modules link and download ogcapi-dggs zip archive.

    The website lists active nightly builds to provide feedback to developers, you may also browse for earlier branches.

  3. Extract the contents of the archive into the WEB-INF/lib directory in GeoServer.

    Warning

    Verify that the version number in the filename corresponds to the version of GeoServer you are running (for example geoserver-3.1.0-SNAPSHOT-ogcapi-dggs-plugin.zip above).

  4. Restart GeoServer.

    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"/>
