The onlin tigermaps are a spherical projection; the NWS shapefiles are 
unprojected lat/lon.  We don't support a spherical reprojection via 
xastir at this time, more's the pity (THAT'S NOT A FEATUER REQUEST), 
because, among other things, it's a less than common projection format, 
proj4 isn't doing the reprojection and gdal isn't up to speed for us 
yet.  I know it's all on the list, but even as one of the resident 
geodesists (are there others on here?) I'm not concerned.

It's "just a hobby" (sm, copyleft).
