Topos US is an app that provides access to download and view high resolution USGS topographic maps for the United States.
REGARDING MAP DATES:
You will often see a date on a downloaded map that seems pretty old. This is the date of last physical survey. This could be a long time ago. Often maps will be compared to aerial photography to verify buildings but not always. I can't do anything about this and besides, mountains don't move that quick.
See the "Currentness Year and Version Year" section here: http://egsc.usgs.gov/maplists/howtoselectmaps.html
This app includes 49 states, with most states having over 99% of the maps for the state.
Please note the following:
Alaska is not included.
Most of North Dakota and Florida are missing.
Access over 50,000 USGS Topo Maps, zoom, pan, rotate, etc.

Review Responses:
FishMike: Pinch to zoom in/out is in the app. Can you get in touch with me so we can figure out why it's not working for you?
v1.5
Maps will now open in the application registered for JPG viewing, most likely Preview. This is a last step effort to bypass inconsistencies across versions of Mac OSX with respect to a particular user interface object that was being used. Hopefully this allows for greater flexibility with what you can do with a downloaded map, i.e. duplicate, crop, rotate, print, pinch zoom, etc.
If you have questions or comments please email [email protected].
