 The main advantages of OSM over Google Maps are that the maps:
   * are more [[#up-to-date]],
-  * have [[#more_trails |more trails]],
+  * have [[#more_trails |more trail information]],
   * have lots of [[#different_layers| different layers]] (like topographic information), and
   * can be used [[#offline]], which is a big one for emergency preparedness.
 ===== Some Links =====

 ===== Different Layers =====
-OSM also has different layers that highlight different information.  The **CycleOSM** and **Cycle Map** layers are very useful since they add topographical information.  Public GPS traces uploaded by the community can also be added to any layer.

 ===== Offline =====
-The biggest advantage (from an emergency preparedness perspective) is that OSM can be used offline using various apps.  One that I particularly like is [[https://organicmaps.app/ |Organic Maps]].  It's available on [[https://apps.apple.com/app/organic-maps/id1567437057 |iOS]], [[https://play.google.com/store/apps/details?id=app.organicmaps&hl=en |Android]], and Linux (as [[https://flathub.org/apps/details/app.organicmaps.desktop |Flatpak]] or [[https://repology.org/project/organicmaps/versions |other packages]]).  A monthly update of the maps can be triggered manually from the app.

-==== Linux ====
+==== Android ====
-Here's Organic Maps on my desktop:
+Since the GPS receiver on Android phones has nothing to do with cellular or wifi reception, Organic Map can be used anywhere in the back country there's a clear view of the sky (to get a good GPS lock).

-Different areas can be downloaded locally with a few simple clicks.  All of Canada takes a bit over 3 GB of space.
+Here's how to get the GPS coordinates of a point on the map (for example):
-{{ :howto:openstreetmap:omapslinuxdownload.png }}
+  - Touch and hold the map at the desired location to get a blue dot
+  - Drag the lower menu upwards to reveal the coordinates
+  - Touch and hold the coordinates to see options of which information to copy to the clipboard.

+</WRAP>
+Conversely, use the search icon to input coordinates to show the point on the map.
-Rightnow, the option to delete individual areas doesn't seem to be working very well but the individual files are located here (at least on the Flatpak install) and can be deleted manually:
-  ~/.var/app/app.organicmaps.desktop/data/OMaps
-==== Android ====
 Updating the maps on Android is a two-step process:
-  - The app itself must be updated (from the [[https://play.google.com/store/apps/details?id=app.organicmaps&hl=en |Play Store]] or [[https://f-droid.org/en/packages/app.organicmaps/ |F-Droid]]).
+  - The app itself must be updated monthly (from the [[https://play.google.com/store/apps/details?id=app.organicmaps&hl=en |Play Store]] or [[https://f-droid.org/en/packages/app.organicmaps/ |F-Droid]]).
-  - The maps can be updated from the app.
+  - Then, the maps can be updated from the app.

+==== Linux ====
+Installing Organic Maps on a computer could help EOCs manage resources over the radio when the internet is down.  Maps can be searched or even printed for field work.  Different areas can be downloaded locally with a few simple clicks.  All of Canada takes a bit over 3 GB of space.
