What The Peak (com.ericpanorel.arcanada) on Google Play
This is a free augmented reality application leaning towards an offline source use case. This is particularly helpful especially when travelling through the mountains where there is no internet connection. Of course, the application will also work with online sources, particularly from GeoNames (http://www.geonames.org/) and from Natural Resources Canada GeoNames service (http://www.nrcan.gc.ca/home). Using the feature class codes (GeoNames.Org) and Concise Codes (NR Can), you can filter which feature you want to be displayed on your Android device. The App defaults to mountains and lakes. You can change them in the Settings page.The offline feature of this App has been targeted to work primarily in Canada (default). Since GeoNames is one of the primary sources, to target this app to your place of interest, simply change the GeoNames zip file source setting.
