[Xastir] Xastir on Mac . . . download, unzip, store maps

[T Wegner]

Not having a lot of luck here, probably because I don't' understand Unix

I would like to download some maps

an example is

wisconsin.osm.bz2

found here

http://downloads.cloudmade.com/north_america/united_states/wisconsin#downloads_breadcrumbs

i used my regular gui to download it to my home directory

then used x11 to move it to the /usr/local/share/xastir/maps directory

tried to unzip it, but got an error message, which i guess makes sense  
as it's not a .zip file


1) am i even remotely close to doing this correctly?

2) this seemed like the map i would most likely want - does anyone  
have any idea if it would be a good map to use for navigating around  
wisconsin or would the wisconsinshapefiels.zip be a better choice. I  
will be perusing the site to try and find info about the different  
maps. there is quite a difference in file size.

tnx
