The vector tile schema has been developed by Klokan Technologies GmbH and
was initially modelled after the cartography of the CARTO's Positron basemap
with permission from CartoDB Inc.
The vector tile schema has been refined and improved in cooperation with
the Wikimedia Foundation and is heavily influenced by years of
Paul Norman's experience of creating maps from OpenStreetMap data.
