[Xastir] Map.GEO files

[Fred Hillhouse]

Hi Curt,

I posted a question on the Xastir list but haven't seen anything yet and
getting impatient! :)

Do you know what tool is used produce the map files, in particular the GEO
file which looks like it contains the calibration for the appropriate image?

On the link below, I see there are some map files and they mention they are
compatible with Xastir. This got me thinking about possibilities.

Also, I remember sometime ago that Xastir could get the OSM tiles. I thought
they could be cached for offline use. Is that true? I am having a discussion
with someone working on getting Xastir running on a Raspberry Pi.

Thanks much!

Best regards,
