Hi Martin,

Thanks for your question... Jan (the project manager) forwarded me your
email, but I have been away...

You're right that this is not ideal. Bing is the only source we have access
to at such scale (and the only source we can use in MapSwipe as it stands),
so unfortunately it is a case of something is better than nothing. The team
in the field is in need of the data for February and are aware of the aged

Happy to continue the discussion but it won't be for a couple of days as I
am heading out the door again now and will be offline until the 3rd. Really
appreciate the feedback...
