[Xastir] Maps Offline?

[Jerry Dunmire]

Hi Kurt,
I'd like to know more about why the OSM tile cache dosn't work off line for
you. I have verified that the tiles work off line for me and I can't (yet)
see a problem in the code.

If you can send me coordinates, zoom levels, and OSM styles you are using, I
might be able to recreate the problem you are seeing.

I would also appreciate hearing from others who are (or are not) have
difficulties using the OSM tiles off line.

73,
...jerry

Xastir use. I stick'em in the directory then unzip them. They are ready to
go right away. I know, not the latest and the greatest but the simplest to
setup in my opinion. Trying to download the latest Tiger maps is a pain. Try
to do each individual county and when I did it, I got a jumbled mess.

download the maps with varying resolutions directly and use them again

everything in there. I kept pulling and installing code like gdal and when I
got down with ./configure, I perused what it told me was in my machine, and
if I didn't have it, I went out and got it. Keep doing a make clean and when
I saw all the different display supports were there,
