How To Use Map Packs, GPX and KMZ files

.

  1   Install the free, open source CoMaps smartphone app. No account needed.
Follow prompts to download topographical OpenStreetMap basemaps of your area.

  2   Download the Map Pack or file.
Note where it's saved. By default, it's probably in your phone's downloads folder.

  3   Import the Map Pack or file.
In CoMaps, tap the three dots in the top left corner and choose Favorites. Select 'Import Favorites' and locate the Trailspotting Map Pack file on your phone. Map Pack is now visible when you return to the main map.

Notes for use:
• Downloaded Trailspotting Map Packs and OpenStreetMap basemaps do not need cell service. Carry a smartphone battery backup when using for navigation, along with your usual hiking essentials.
• Our Map Packs and GPX files can be used for navigation, but only in conjunction with a downloaded OpenStreetMap basemap. They are provided for general reference only. See our full terms of use and disclaimer linked at the bottom of the page.
• New England Rail Trail shows routes that are approximate and should not be used alone for navigation purposes.
• We hope to add better map placemarker types and colors as soon as CoMaps improvements allow.
