Finding Your Way with Maps and GPS
Since most Android devices have a GPS (Global Positioning System) receiver, they can be
used as a powerful mapping and navigation device. Using Google Search and Google Voice,
you can find places and get directions right from the search bar on the Home screen. These
maps and directions are powered by Google Maps, but you can install other navigation and
map apps to extend the capability of your device.
There are several different types of maps that are useful on Android devices. The most
popular are street maps for city and highway navigation, and topographic (topo) maps for
backcountry and outdoor navigation. Most everyone finds street mapping useful, while topo
maps are primarily used by hikers, hunters, and others engaged in outdoor activities.
Aviation and marine charts are specialized maps used by pilots and boaters.
Warning!
Never depend solely on an electronic device for wilderness navigation. Even though many
Android phones and tablets have remarkable battery life, it can't be compared to a paper map
with a “battery life” of infinity. Also, many mapping apps require an Internet connection for
access to maps. You won't find Wi-Fi hotspots in the wilderness, and LTE is not available in
most remote areas.
Dedicated trail GPS receivers are still far superior to tablets and phones for backcountry use.
Trail GPS receivers have more sensitive receivers that can maintain a satellite lock under
more difficult conditions. They also have longer battery life, from 12 to 24 hours or more,
and most use field-replaceable AA or AAA batteries.
Bottom line- always carry paper maps and a reliable compass to back up your electronic
navigation, whether tablet, smart phone, or trail GPS receiver.
