Much of the track is gone. (Compare the SDFI map with the older Esri map.)

The hiking routes may need to be updated.

Der er en lille alkove her. Hvad formål har den tjent?

Which way does the water flow through here?
The water is depicted lower on the eastern side, but the only waterway to the sea that I can find is on the west side through Hunså to the northwest.

Hunså begins at 9 m above sea level, and is represented here:

These bike routes are not very precise.
Consider redrawing them using the SDFI Terrain Shadow Map, e.g. using the iD-editor.

Part of the path here has fallen into the sea.
Should the path be removed from OSM?

Highways have been placed on Møns Klint with rather low precision, and as a result they cross waterways in many places.

If someone is familiar with the highways, consider correcting them using the SDFI Terrain Shadow Map which is available in the iD (in-browser) editor.

What do you call this? it's like a manhole cover, but is 1.5m wide; too wide for the wiki definition. It also extrudes ca. 10cm from the ground.
man_made=manhole

Hvad er dette område? Jeg menes at skiltet siger "drikkevand invindes her", men jeg ved ikke om dette punkt skal markeres som man_made=water_works, man_made=pumping_station, eller noget tredje.

Jeg har markeret Stensved Vandværk mod syd som man_made=water_works.
