Presented by John Krout
All map apps for portable devices depend on two data sources: GPS signals from satellites, and map images from cell towers. Have you ever visited an area where cell phone service is spotty or simply not available? There are many such places in the US, including popular national parks. That condition makes it very difficult to use apps such as Google Maps or Waze to navigate. Those apps depend on downloading maps via cell towers, and stop displaying maps when cell towers are not accessible. This demo will show you how two Android map apps, and similar software for the Apple ecosystem can use offline maps, meaning maps stored on the phone or tablet. These maps work just fine when cell tower service is either not available, low bandwidth, or when demand exceeds supply, meaning a crowd is overtaxing the one and only nearby cell tower. It turns out that downloadable offline maps for the entire US, Canada and western Europe are available online for free.
