[OSM-talk] Outdated shapefiles

[Andre Hinrichs]

Hi!

I'm not very familiar with this area.
The edits moves the coastline partly more than 15km to the south.
But according to "Esri World Imagery (Clarity) Beta" I would move the
coastline even another 15km more to the south!
Don't know if the accuracy of these images in that area is guaranteed.
So, from my point of view it looks better than before.
The line has also the tag "glacier:edge=calving_line" and I would say
this should be the line of summer...
Ice shield is shrinking as we all know due to the climate change.
And that means that there will (unfortunately) be relevant changes in
the near future until there is no more shelf ice.
