redundancy

[totient]

I wish I had a USGS map browser which was also aware of Census Bureau map data. I can usually tell the intended road on a rally course, but not always. As it is, when I run into an ambiguity, I have to split my time between the (wonderful) topo browser I've dedicated five gigs of hard disk space to, and an online browser (Census Bureau being the data that Mapquest et al use). I have the data on CD, but without an integrated browser it's not much use.

Isn't this (overlaying various types of geographical data for simultaneous viewing) what GIS browsing systems are all about? Or is that sort of thing absurdly expensive for the private owner?

(Apropos of nothing, I recently went on a guided tour of some of the (many) map collections at MIT; I highly recommend checking them out, particularly Lindgren, if you're ever around and have the time.)

Try the MassGIS site. They have a Java map browser that lets you overlay topos and aerial photos with road names, railroads (it actually includes every railroad ever built in the state, including the ones now at the bottoms of reservoirs) and all kinds of data layers. Ghastly slow, unfortunately.

And also MA only. I know most of the rally road names in Massachusetts by now anyway. But tracing out old rally routes in Vermont is being a pain in the butt.
