Is there available any ortophotomap layer (WMS, TMS. WTMS) for Norway area with higher resolution and quality than Bing aerial imagery? Of course, to be used legally for OSM mapping purpose. Best regards.
I tried finding something and asking on the mailing list, and I even asked Kartverket I think but no luck. In the future perhaps, but not for the time being.
At least the DigitalGlobe Premium imagery (available e.g. in JOSM) usually has much smaller offset than the Bing imagery. So I tend to prefer using DigitalGlobe Premium instead of Bing.
In addition, I always compare with Norgeskart and Strava heatmap to ensure that the offset isn’t too large.
