As the years passed, the USGS produced new map versions of each area. The most current map of each area is available from The National Map. TopoView shows the many and varied older maps of each area, and so is especially useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the historical names can be found on many of these topographic maps.

The US Topo production schedule follows the U. This does not include US Topos for Alaska, which are on a different schedule. The linework features shown on the maps are generated from US Topo maps are as accurate as the data sources used to make them, but because these sources are many and varied, it is not possible to make a single simple statement that the map as a whole meets a particular level of accuracy.

US Topo maps, therefore, do not have a traditional accuracy statement in the map collar. Accuracy information for individual data sources is included in the metadata file Bulk delivery is available for maps from the US Topo collection produced present and the Historical Topographic Map Collection produced In bulk delivery requests, please specify which of these two product series you want.

Hi Rich, I lost my Oregon T last fall during an epic mountain bike ride. Very surprisingly it unclipped from my bar mount.

I probably bumped it against something because it was tested very often in hard rides and never had problems. Anyway, shit happens. I bought a Oregon without topo on boxing day deal, telling myself that I would be able to put the topo back in it knowing I got a backup of the entire T, like you suggest on your site. Also I previously bought the City Navigator that was loaded on the T and wanted to put it on the new I am beginning to understand ,sadly, that there may be no way to do that.

Garmin seems to allow a map to only one gps. The question is, knowing that the T is lost, is there a way to transfert those 2 maps on the new gps and shut off the lost one? Thanks for your help on this. Not that I know of. I own a Garmin Montana Route Calculation Error.

Maps do not have routable roads in this area. I have downloaded from your free map site the following free maps. Garmin said I make it work by setting up routing by direct routing.

Any suggestions. Any hints as to how to create one of those transparent trail maps using my Mac? Include the. I just received a Garmin Dakota10, as a birthday present. I may be dropping by again to ask for help!

You have a nice site here! Looking for a auto gps with a 5in screen or larger that can be loaded with topo mapping.
