Intro to Geo PDF Maps
What’s a Geo PDF map? How do you use it?
A Geo PDF map is a map you download and store on your smart phone. Use the free app called PDFMaps to view and navigate from the stored map in your phone. Use it on hikes or bike rides to log your distance, start time, duration, and more.
You don’t need wi-fi or a data connection once the app is installed. It uses your phone’s GPS feature so it works even if you are out of range of mobile phone service.
Meet at the Visitor Center to see a slideshow and find out how to obtain a copy of a Geo PDF map of the Don Edwards SF Bay National Wildlife Refuge. A live demonstration will follow.
