Topos East is an app that provides access to download and view high resolution USGS topographic maps for the eastern region of the United States.

NOTE: There is a button in the app to quickly email in case of issues. If you have any issues at all, we'll do whatever we can to make it right. We can't respond to reviews, please give us a chance to fix the issue first.

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:

This app includes the following states:

New Hampshire
New Jersey
New York
North Carolina
Rhode Island
South Carolina
West Virginia

Partial maps:
Florida - very few Florida maps are available.
Massachusetts - 61 of 188 maps are available.

There are over 10,000 maps in total. More than 99% of them are available for the states listed.

Some notes on the app:
- This are no frills, just simple, huge topo maps.
- It doesn't show you where you are on the map.
- You can't stitch maps together.
- After a map is downloaded there is short period where the map is broken down so you can zoom and pan, it only happens once for each map downloaded.

Please contact us at so we can resolve any issues quickly.
