Open Space Map Resources: GPS Apps
We recommend the use of a GPS App for some hikes where there are numerous trails and less-than-perfect signage.
What are They?
- They are used to track hikes and to explore areas of town
- They contains a set of maps which show roads, infrastructure, topography, and trails
- An App can track your position, measure your distance, time, and elevation, and provide a track of where you went
- At every point you can see where you are in relation to roads, buildings, water, and trails
- An App can also allow you to plan a walk through an area
- You can see how close you are to the track as you explore
Where to Find
- You can find information about these tools by doing a web search
- They are most frequently downloaded from an App Store on a mobile phone
- GPS Apps typically come as a free download, with an option to add features for an annual fee
- The two most popular features are additional base maps (for example satellite view) and downloadable maps so that maps are available when off-line
Two Popular Apps
GAIA
- Popular with hikers and bikers
- Some feel it is a little more complicated to start with than AllTrails
- Many frequent users like the interface better than AllTrails’
- Clicking on the Trip icon at the bottom provides more information such as elevation gain and loss, time moving and not moving, average speed, etc.
- You can store all other hikes in the area, which can also be displayed on the screen for reference purposes
AllTrails
- Covers the same basic functionality
- Has a large database of user-submitted hikes with ratings that some people use to select hikes
GAIA Example

- This hike was done in the White Mountains, starting near Waterville Valley. We took the trail up to the Greeley Ponds and returned the same way.
- The green line on the map shows the track taken
- The triangle shows the location when the screenshot was taken
- In this case we were nearly back from the hike, which was 6.28 miles and was done in 3 hours and 30 minutes
- You can see roads and other trails in the area, and also the topography of the trails.
