A contact in Microsoft said that the Bing imagery is made up of multiple images which results in the date range. The imagery we are getting has improved over time, although it seems at a snails pace. I'm sure if we were paying for imagery we would have different requirements. Bing probably wants n

There's no technical issue at all, he can see the meta data. Microsoft can push what ever meta data they want or none at all. I was just suggesting a solution to Christoph's issue with lacking meta data On Tue, Jul 25, 2017 at 1:56 PM, SwiftFast wrote: > OP asked a about a very specific technica

In an ideal world there would be as many skilled mappers per square kilometre as there are in Germany. Unfortunately the density of mappers available elsewhere is not the same. In many parts of the world there are very few maps and these are not of a high quality. HOT and the missing maps projec
