Topo Maps US6.8 - App Store

Download USGS topographic maps of the United States and use them offline, with no account and no subscription.

Topo Maps US is built for people who go where cell service doesn't: hikers, backpackers, hunters, anglers, paddlers, mountain bikers, geocachers, and anyone who wants a real topographic map in their pocket.

MAPS
Choose from three USGS map layers: standard topographic, aerial imagery with a topographic overlay, or plain aerial imagery.

OFFLINE
Tap the map squares you want and download them before you leave. Downloaded maps work with no Internet connection and use no cell data in the field.

TRAILS AND POINTS OF INTEREST BUILT IN
Every map download includes the trails, summits, lakes, campsites, and other named places in that area from OpenStreetMap, so you can search them by name while you're offline.

TRAIL RECORDING
Record where you go. Recorded trails show your path on the map with distance, elapsed time, and average speed. Recording stops automatically when you start driving, and any drive at the start or end of a trail is trimmed off.

ELEVATION PROFILES
Every recorded or imported trail gets an elevation profile with distance labels and color-coded grade shading. Drag along the chart to see the matching point on the map, its elevation, and the time you passed it.

FLAGS
Mark your current location or any spot on the map. Flags record coordinates and elevation, and you can add notes and organize them by color: geocaches, trailheads, summits, camps, and so on.

NAVIGATION
Pick a flag and follow the direction arrow, driven by your compass heading, with the distance remaining. Handy for geocaching and for finding your way back to camp or the car.

LOCATION
See where you are on the map, your elevation, speed, and the accuracy of the GPS fix.

MEASURE
Trace a route on the map to measure its distance, then save it as a trail to follow later.

IMPORT AND SHARE
Import trails and waypoints from GPX files and geocache LOC files. Share your flags and trails by email, Messages, or AirDrop as standard GPX files that work with any GPS unit or mapping software. Back up your maps and data to a computer over Wi-Fi.

Designed for iPhone and iPad.

Note: Continued use of GPS in the background can noticeably reduce battery life.

Version History • Recording stops when you start driving. Finish a hike or ride and drive off, and the app notices, sends a notification with Stop and Keep Recording options, and trims the drive from the saved trail. Turn it off in Settings if you prefer.
• Trim drives from older trails. Open a trail that ends with a drive home and the app offers to remove it.
• Cut a trail anywhere. Scrub along the elevation profile and tap the scissors to drop everything before or after that point.
• Save polyline measurements as trails, not just freeform ones.
• Elevation profiles for imported routes and saved measurements now follow the terrain between widely spaced points instead of drawing a straight line.
• Fixes for flags that never got an elevation, plus memory and stability improvements. 6.8 2d ago • See when you were there. Tap any point on a trail you recorded and the popup now shows the time you passed it, along with elapsed time since the start. The time also appears in the elevation panel as you scrub along the trail.

• Trails without elevation data (like imported GPX files) now have an "Add Elevation Data" button in Trail Detail. One tap fills in the full elevation profile.
• Trails and flags included with downloaded maps now get elevation data automatically.
• New flags are automatically filled in with the elevation.
• Tap any point along a trail to see the distance and elevation at that spot.
