[Xastir] Online Tiger maps server?

[Craig Anderson]

Hi all,
	I found the new 2008 version of the Tiger maps at the Census web site  
and tried to get them to work with Xastir but most of the dbfinfo  
strings have changed (and even some files have disappeared).  That  
means I have to go through all the hassle of reworking the dbfawk  
files again.

My question is, how does the online Tiger map server generate such  
good-looking maps?  I realize they are raster maps.  What I wan to  
know is how they pick the features to display and how they layer  
them?  Is there a web site for the server that explains anything?  Who  
provides that map server?  What version of Tiger maps are they based on?

Any pointers would be greatly appreciated.

Thanks,
Craig
