Available ortofoto årgange (no key)

Ortofoto årgange the upstream publishes, newest first, derived from its GetCapabilities. NOTE: coverage is REGIONAL per year — Denmark is flown in a rotation, so most points are covered by only a few of these years, and this list is what the SERVICE publishes rather than what covers any given point. A tile request for a year that does not cover the requested tile answers 404 rather than the upstream blank image.
