Hello,
I am working with USGS topo map quads and ran into a bit of an issue. Some of the quad's have roads overlays and others don't. For example I'm working in northern Oregon, Washougle and Multnomah have roads, but Bridal Veil, in between the two doesn't. I've looked everywhere I can think of, USGS, Geo Community, TopoZone but no luck. Can anyone help me fill in the holes?
Thanks, Dan

Interests:I am a Cartographer with varied experience. I work primarily as a freelancer. In my freelancing career I have worked with Maps.com, Designmaps.com, 3dmaps and various other map making and cartography sites.
I have varied software experience, however I use almost all the Cartography and quite a few GIS software, Illustrator, Freehand, Adobe Photoshop and Mapinfo to be precise. I have also worked on Microstation and other Intergraph software including Stereo Photogrammetry on ZI Photo Suites. The other software that I utilize for various other tasks specially 3D realism are Global Mapper and Maprenderer 3D.
Global mapper is a versatile software for various conversion and I found Maprenderer 3D for producing stunning 3D images from height data.
I am available for freelance work, right from mundane line digitisation to Illustrator / Freehand Cartography. Just send me a mail at promapper@gmail.com -

Hopefully someone can back up my reply with better info, but from what I can tell, relatively few 1:24k quads ever had their linework digitized into a vector format. I think that's why companies such as Topo Depot exist. How have others dealt with this problem?

Hello Dale,
It seems you are right about the quads. There are a lot of holes out there. I found a tutorial on working with Tiger in Manifold. Hopefully, this will help other start-ups bridge this gap http://exchange.mani...GERTutorial.htm
Thanks to both of you for your help.
Dan
