Topo Nomad8.1 - App Store

Download high resolution USGS topographical maps for offline GPS* use.

Topo Nomad is designed for road trips, camping, hiking, exploration and geographical history. Map images are accurately center aligned regardless of datum and placed on top of Apple's map kit for easy referencing and intuitive touch navigation.

This software utilizes the latest capabilities of IOS offering the highest performance with fast start up, map rotation, rendering and zoom with unbeatable details and undistorted resolution. Map downloads are dispatched in the background so you can continue using the app while new maps concurrently install.

Topo Nomad indexes of over 250,000+ U.S. Geological Survey current and historical topographic maps describing the topography of every region and island territories of the United States of America. Historical versions date as far back as year 1884. Install a map quad by pressing and holding a point on the reference map and discover the USGS historical maps available at that coordinate and the unique names given to every quad by the cartographers.**

The limits don't stop there with just USGS maps. Import "Geospatial PDF" maps from the web, iTunes and email. Many local and national park services offer PDF map downloads from their web sites which automatically install into the Topo Nomad app. And, if you reside outside the United States check with your government services for topographic and aeronautical sectional maps with embedded geospatial metadata.‡

Cannot find that map you downloaded but know where in the world it's located. Simply zoom out the reference map view and all the topo maps become a colorful violet and partially transparent so you can spot your map. Installed maps are managed in a table format which can be sorted by name, distance, and scale. Multiple versions of the same map can be stacked on top of one another and made visible or hidden using two finger swipes.

Planning a hike somewhere and want to know the distance of your jaunt. Download the map and use the dual mode ruler to measure the path distance and know the answer to "how much farther?"

Purchase a subscription for unlimited map downloading. A subscription stops ads and doesn't auto-renew. The first few map download are complementary.‡

Version History • Nice speed improvements.
• New PDF rendering engine that is significantly faster and properly displays the USGS USTopo map series.
• No google advertisements and no trackers. 8.1 11/07/2022 • Improvements for Track & Routes.
• Reference map has OFF mode so not to fetch image tiles from Apple map server, reduces network data use.
• The home button arrow no longer points with true North unless the map is manually rotated. 7.2 03/27/2019 Geographical search service running with a new data source.
Compatibly improvements on KLM file imports for placemark tracks. 7.1 11/28/2018 - UTM/MGRS support for Numerical Location entry within the grid zone current being viewed at the screen center.
- Stability fix.
- Supports iOS 11 and later versions. 7.0 09/18/2018 Now supports Military Grid Reference System (MGRS) and Universal Transverse Mercator (UTM) coordinate formats. Entry of MGRS, UTM or geodetic coordinates formats is recognized automatically by the parser. 6.5 09/12/2018 • USGA map index updated to June 2018.
• Improved map downloads from faster and reliable servers.
• Software security update. 6.4 06/05/2018 • Bug fix: The distance units defaults to metric, or statute units depending on locale setting, and remembers the last units setting.
• Waypoint callouts notes supports HTTP web links and HTML text format, first characters must be " 6.3 03/06/2018 Fix for iPhone X screen size.
Route and Track view improvements. 6.2 01/03/2018 Fix made for imported maps using the datum meta-typed as geographical.
Memory stability improvements for rapid panning and zooming. 6.1 12/10/2017 • New feature to export waypoints, routes, and tracks in GPX file format to email and SMS text recipients. 6.0 10/05/2017 Location indicator shows loss of GPS signal and reacquiring status with a light green arrow color, which can occur when in forest or entering a large building. 5.3 07/06/2017 Thank you Apple for IOS 10.3.
• Performance.
• Tracks and routes show path point distance when tapped.
• Current US Topo maps draw PDF OCG defaults without aerial image layer (IOS 10.3).
• 25K scale and smaller maps will release hi-res image data should your device storage space becomes critically low, drop in resolution is negligible. 5.1 04/15/2017 • Waypoints AR
• Performance 5.0 10/06/2016 GPX improvements with route tracks and waypoints.
Supports CDATA XML data in imported GPX files. 3.8 05/26/2016 • Performance improvements!
• Restore and sync map download selections from other iOS devices and for app reinstall. 3.7 04/27/2016 • Performance Improvements – Older iPad and iPhone models may notice a significant improvement in UI responsiveness.
• Track recording now records while not using the app since a new property setting is required for location services to run backgrounded in iOS9 3.6.1 03/04/2016 • Track and Route path merging will create a new path instead replacing the matching name. Tracks are merge by metadata timestamps, routes merge by the order of the existing name being append with the renamed route.
• Added data recovery for waypoints, tracks, routes if app process is terminated while writing to storage or if app is blocked from running in the background while busy saving and the device is put to sleep; resolves a bug fix in waypoints migration from older 2.x version. 3.6 02/18/2016 • Track recording and Route paths.
• Waypoint have several new symbols and allow for grouping.
