Maptitude - http://research.umbc.edu/~roswell/maptitude.html
I'm interested in purchasing the CDs, but I didn't see any mention of them
on the Web sites listed in this thread. Can you provide me with a contact
phone number or URL for the CDs. Thanks.

The problem with these data is that the CD contains all of the image and
projection parameters neatly encapsulated in the GeoTIFF file, but the data
on the FTP site require you to hand-build the .HDR file without providing
you with its format!
(Richard and I have been having an exchange on the side, which should
result in a template for the .HDR file that others can use.)

That is because the vectors are (or can be converted to)
longitude/latitude, which then can be displayed in any
projection/coordinate system that is appropriate. The rasters are images of
the earth that have an inherent projection/coordinate system, and for the
vectors to line up you have to identify that projection/coordinate system.
