Dave,

I followed the link to the routable Garmin maps that you have made
available. I'm assuming that these are for the US since they are on the
US mailing list. However, the contiguous US (CONUS) goes from
approximately -66.5 to -125. I didn't see any of the ranges that you
have that will go this far east in the western hemisphere. Am I
mistaken about the extent of CONUS?
So, this isn't the continental US that I'm talking about. The algorithm
looks like this:
for each garmin image...
does it intersect a state polygon?
If so, add it to the set
The result will be clear if you look here:
http://garmin.na1400.info/routable.php
in the very upper-right corner. See the few Aleutian islands that cross
180/-180 longitude?
So, the images are named a bit strangely. The names mean:
This image contains all of the tiles which have middle points
between these two latitudes.
The end result is that I put the Aleutian island tile next to Maine.
I'm too lazy to fix it at the moment. :)
