Open Street Map data as source for map

40 feet elevation contours with dem/3d shading from 3" SRTM data

Limitied poi's for less clutter

The "Windows" version is the .img file and can be directly copied or installed to the Garmin folder on your GPS (on older, single mapset devices mapname may need to be renamed gmapsupp.img), or copied to Orux/mapfiles folder. 

Orux is available on the Google Play Store however older versions are no longer available on the author’s web site and states they are depreciated as of August 2024.  Free versions of Orux, 7.26.xx, may still be found on 3rd party sites.  

To view maps in Basecamp on Windows use the "Mac" version, after extracting and opening to mapaname.gmap, mapset can be placed in the Windows C:/ProgramData/Garmin/Maps folder (may need to un-hide and create)  or installed to Mac using it's install process.  Those using Chrome or its variants to download  the Mac version will need to click download and then right click here (underlined) , copy and paste the link into a new address bar for the download link to appear.

Updated: Added road shields, changed some road coloring and other minor improvements

Update 11/29/20:  State/Province names now visible; changed dem/3d values, reducing map size with little visible difference to shading or 3d view

Update 2/21/21:  With this update most Native American Reservation land boundary's now visible

Update  9/6/21:   The following Native American Reservations land boundary's are now visible;  Fort Peck, Fort Belknap, Rocky Boys, Northern Cheyenne, Wind River, Fort Hall and Duck Valley.  Previously I attempted to add, because it doesn't exist in the raw data or modify that data in JOSM to become visible, These had mixed and poor results.  Recently with the help of QGIS and Map Edit++ I was able to succesfully get the above listed Native Reservations to render

Update/Bonus 3/20/22:   Map updated with current Open Street Map data and several minor changes to the Topo map.  Included in the zipped archive for the Windows and Mac versions is the Topo map AND a routable version of the map for the same area.  These bonus maps have no contours or hillshading, but do have additional poi's and and are routable, though YMMV

Update 7/17/23:  Map updated with current data

Update 2/17/24:   Map updated with current data, also resolved issue with duplication of some roads seen in Basecamp

Update  2/2/25:    Map updated with current data.  An exception was/is missing border segements with South Dakota and Nebraska.  The osm data from geofabrik is missing much of the border as seen in my previous map and seen in others maps as well.  I was able to kludge and merge border data from other sources and now only a couple small gaps in the border remain..
