* Supports WCS versions 1.0.0, 2.0.0 and 2.1.0.
* Richly featured styling engine for serving data visualisations via WMS and WMTS.

Known CRS Limitations
---------------------

1. ODC datasets with WKT-format CRSs will not work with OWS - data from such datasets
will never be displayed. OWS currently only works with EPSG format CRSs.

2. Datasets that straddle the anti-meridian or the north or south polar region will
cause issues with the legacy postgres driver.

These are fundamental limitation of the way OWS works with the postgres ODC index driver.
These limitations will be addressed in v1.9.0, but only for the new ODC postgis index driver.
