Topo Map of Alaska

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

TYP included, user can change many visual elements with typviewer or typewiz

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 2/8/21:  Filled in missing boundary's of the Alaska State Park system also filled in trails of the State Park system which were incomplete.  National Park Service, US Fish and Wildlife, BLM and US Forest Service boundary's have mostly been filled with this update. 

All data was downloaded from the respective land management department.  Only tag edits were conducted for processing purposes.

Update 1/20/22:  In the Southwest part of the Alaska, specifically the Kusko/Bethel area, much of the area would appear flooded would without additional processing that I conducted as the raw data was not condusive to a "nice" looking map for the area. This mapset is slighly larger than the previous, upzipped a little over 2 GB, but is up to date and may have a few more features available to the user.

Update/Bonus 2/12/22:   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 2/24/24:   Map updated with current data, also resolved issue with duplication of some roads seen in Basecamp

Update 1/24/24    Map updated with current data, See above 1/20/22 update, further processing still required to eliminate "flooding".  This processing removed the names of several rivers, most notibly the Kuskokwim.  Some further tag edits to the raw data has restored the names as best as I can see.
