One question is how they encode E/S i.e. negative coords; e.g. it could be via binary complement or it could be via adding half the range to the value to make it positive (i.e. coded lat = lat + 90; coded lon = lon +180).

International Expansion

With this release, we have expanded international coverage of maps and imagery, including the first bird’s eye outside the US, namely in the UK (here’s a collection with some of the highlights). We will continue to expand the coverage of bird’s eye across the US, UK and other areas, rolling out additional imagery on a regular basis.

Aerial imagery has also been improved. In the UK, we have detailed aerial imagery of most of England and We also have improved the base level coverage for aerial imagery, bringing it down to level 13 world wide, from level 8 previously (see here for details on level 13’s resolution).

We have expanded road map and routing/directions coverage to a number of countries (English only, localization will come later). UK and Canada both have major highway and city/town level detail for maps and routing. Western Europe, Australia, and a few other areas have city to city routing on major highways and thoroughfares.

If these are base36 numbers, they don't appear to be directly propotional. Given the proportions of the two longitude vlaues, following a mathematical progression, I would expect to see roughly the following correspondence if these numbers are at least proportional (and in base36):

Ya know, I was just thinking the same thing this afternoon as I was digging a ditch.

You brainiacs keep working on this please. I've got the first A -IF in GB on LL BE bookmarked and ready to post.
