[HOT] Bing coverage analyzer Syria overview

[Harry Wood]

Hopefully the bing imagery analyzer (green and red coverage map) is now giving a more helpful overview of coverage in Syria:

The system gets a bit confused when bing adds new imagery in an area. You can zoom in on a red patch and it turns green. The zoomed out overview ends up being a bit useless. But I have written a script which solves this by re-requesting all red tiles in an area then requesting to re-generate the pyramid of lower zoom tiles. Bit of a brute force solution to the problem, but it seems to have worked. I ran it overnight for Syria
