I have been discussing with others about improving the quality of GPS 
navigation software available for linux.  We would like to come up with 
a GPL solution that is competitive with the products you buy from 
delorme, microsoft, rand mcnally, etc...

We think that we want to get the data from the Tiger/Line files and 
convert it to something better.  We would need to the database to work 
so that parts of it could be downloaded by region to a device (ie, maybe 
you want just the State of California and major US highways on your PDA) 
and we would need to database to work fairly quickly for the moving map 
a) Would PostGIS be a good candidate for this purpose?  Would you 
recommend something else instead? 
b) How does it compare with commercial databases like Navtech's when 
used in this fashion?
