Guyute Posted May 23, 2002 Share Posted May 23, 2002 I was just wondering if all of the mapsource products have accurate streams and rivers. I also would like to have bridges listed. These are the most important in my decision. Any help, thanks Quote Link to comment
+Alan2 Posted May 23, 2002 Share Posted May 23, 2002 Check out the Garmin website garmin.com and you can download samples of all their mapping products and check for yourself. Alan Quote Link to comment

I also would like to have bridges listed. I looked at several topo maps (Mapsource, ExpertGPS, Topozone and Maptech), and I've learned that all topo maps in the US are based on the quite old USGS maps. Practically you'll get exactly the same quality when you visit www.topozone.com. If you're happy with what you can see on the topozone website about your area, than it's highly probable that you'll be happy with all other topo maps. Unfortunately, I'm not very lucky: the topo maps of California are not updated for at least 20 years. On these maps about San Diego, for example, you can find valeys, creeks that disappeared long time ago because of urbanization. Quote Link to comment
+Alan2 Posted May 24, 2002 Share Posted May 24, 2002 Mapsource Topo is based on 1:100,000 scale so its details are a lot less than USGS 7.5 quads and topozone maps which are based on 1:24,000 scale. However, I use Mapsource Topo in my Vista and find it useful even though I carry along printouts of the 24,000 maps. I cross-refernce m locations. Good luck. Alan Quote Link to comment
