GPS Video Tutorials

I'm a serious hiker and not-so-serious kayaker, a septuagenarian, retired from a three-decade Silicon Valley career writing about and for technology companies. 

In 2016, strictly as a hobby, I began making video tutorials about OsmAnd Maps & Navigation, a GPS app with extraordinary features and, at the time, confounding documentation (now much improved). I've since done videos on Custom Maps and Avenza Maps, which both make use of raster maps. Also linked here: my video essay on how the crowd-sourced project OpenStreetMap has become the world's trail map. I had hoped that one would go viral. I'm still hoping.   

Custom Maps (Android)

Custom Maps is an Android (only) GPS app that can use almost any digital map, whether found online or photographed out in the world. These maps often show features that are unavailable, or less clear, than those found in conventional GPS navigation. Created by Google engineer Marko Teittinen, Custom Maps is the only app I know that can both georeference a digital map and use that map for navigation.


OsmAnd Maps & Navigation (Android & iOS)

OsmAnd primarily uses data from the OpenStreetMap project.  It can do turn-by-turn navigation on hiking trails as well as roads. It can record GPXs and follow them; estimate distance, ascent and descent; show an altitude profile and an analysis of the climbs you'll encounter.  It can show contour lines, hill shading, and points of interest. OsmAnd also works well as a tour guide, showing nearby sights that have Wikipedia articles and letting you read those articles offline.   

Except where noted, all videos use OsmAnd's Android version; the iOS version is similar.

The data source for OsmAnd's offline vector maps, OpenStreetMap is the world map that anyone can edit.  


Avenza maps ( iOS and Android) 

AvenzaMaps is a GPS app known for its large, worldwide Map Store.  Some maps free, others are for purchase.  Users with some technical savvy can also import maps from anywhere online, georeferenceing them using the free, open source QGIS desktop  program.  Compared with Custom Maps, Avenza has the advantage of its map library and the ability to run on iOS.  On the downside,  georeferencing requires a separate, desktop program.  This version uses Avenza's iOS version; the Android version is similar.
