Markus,

   Raster files such as those available in ESRI Grid format include a file
named prj.adf. That's a pretty good clue it contains the projection
informaiton that grass needs to create a location.

   Vector files available as ESRI Shapefiles include a *.prj which grass uses
to define a location's projection.

   The vector files available in ESRI, Garmin, etc. open file grid format
have extensions of .atx, .gdb*, and .spx; at least, those are the ones I
see in the transportation map I want to import. They all seem to be database
files, not projection files. I've tried the .atx and several flavors of
.gdb* without success.

   And, now that I moved ~/grassdata to ~/data/grassdata (and modified
~/.grass7/rc to reflect the new path) grass does not recognize
~/data/grassdata/ODOT2014/ as a location available for selection in the
initial dialog box.

   What I'd like to learn is how to specify a location using .atx or .gdb
files. Then I could move these data in there and import them prior to
reprojecting them to the current project subdirectory. I'd be happy to write
this procedure on the wiki page once I had something useful to write.

Thanks,

Rich
