Why should you download the gmapsupp.img format maps?

As Garmin does not seem to fix MapInstall anytime soon - I've now also made all countries available as gmapsupp.img download - which after unpacking - you can directly move onto your GPS device. Europe and Asia are too big to offer as gmapsupp.img maps - the contourlines are available as gmapsupp.img download however.

Note - this way you loose the possibility to only upload a part of a map to your device as you could do using MapInstall (or Mapsource for Windows users). The advantage is that you can very quickly change the layout (on both Windows, as well as Mac OS x or Linux), and that it's the quickest and easiest way.

If you want to use the maps for planning on your desktop - then you will need the Desktop map too or instead. Note: If you plan a route in Basecamp on your desktop - you should use exactly the same map on your device (so same date, same country - but Unicode/Non Unicode does not matter - so you could use Non Unicode map on your GPS device if needed, and Unicode map on your Desktop/Notebook)

 

- Map Data

All maptiles are compiled with mkgmap using map data from openstreetmap.org & Contributors. You can use and edit the map data by visiting openstreetmap.org.

Contourlines/DEM data:

The altitude data for the contourlines is from varying sources in the following priority (if available):

  1. LIDAR data from open government data and other openly available sources - collected and converted to hgt format by - Sonny - https://data.opendataportal.at/dataset/dtm-austria This data is very very high quality and resolution - there is no better open data available according to my knowledge.
  2. ALOS World 3D30 - überall zwischen N60° und S60°
  3. SRTM 1" v3.0 - very rarely for some tiles missing in ALOS data - also only between N60° and S60°.
  4. Viewfinderpanormas 1" - then 3" - above N60° / below S60° as there is no SRTM data nor ALOS or LIDAR Data avialble.
  5. SRTM v3.0 by NASA 3" v3.0 (very very rarely, 8 tiles only)

more exact info which data is used where - inside the copyright.txt files.

 

Installation:

Unpack with 7-zip (lzma2) .  Recommended tools to unpack:

The default layout is "wide" - the layout optimised for most modern garmin GPS units with comparably high DPI. 

Move the gmapsupp.img file to the /garmin folder on your mSD of your Garmin GPS unit. Note the contourlines (altitude height lines) are always a separate second download - so updates are smaller as the contourlines rarely change. The second reason why contourlines are a separate download is that this way you can change contourlines layout independently from the map layout.

 

If you want to move several countries to your device - you will need to rename the gmapsupp.img file. E.g. just call it mtbmap_Austria.img. Make sure not to use Umlauts or custom symbols ("_"  is okay, better not use " "space. Latin alphabet only)

 

Make sure that the mSD of your Garmin GPS unit is FAT32 formatted. Else it cannot be read by your device. Second - do not forget that most new Garmin GPS devices cannot read Unicode maps - so in that case for maps that have (Unicode) after the name, resort to the non Unicode maps instead.

 

 

If you have not used OpenMTBMaps before - please read through the topic about Autorouting: https://openmtbmap.org/about-2/autorouting/

Map Legend - look at it too so you can understand the map layout better: https://openmtbmap.org/about-2/map-legend/

 

Country-ov.img

This is a basemap of the Country. You can use it if you deleted the original Garmin basemap from your device. In general it's not needed.

 

Compatibility - Unicode vs Non Unicode (cannot authenticate maps)

Newer Garmin devices cannot use free unicode maps (except if you hack the firmware) - usually a "cannot authenticate maps" message which show on boot. The following Garmin outdoor devices are affected:

  • All Garmin devices presented 2016 or newer
  • Edge 1000
  • Epix
  • Etrex 20x / 30x (not "etrex 30")
  • Etrex Touch 25/35
  • GPS Maps 64 series
  • Montana 610, 680
  • Oregon 700,750
  • Some recent Nuvi devices - as well as some super old devices that do not support Unicode. (E.g. Garmin Vista C, GPS Maps 60 C)

you will need to download the "Non Unicode" version of the map. Only maps of regions where several different scripts are used - are in unicode. I've listed the non unicode maps however also unter the unicode header for convenience (actually only maps with (unicode ) following their name are actually in unicode.

Also english version of maps is only available for countries/regions not using latin only.

 

Adapting The Map Layout 

It's very easy to chose a Map layout:

 

Windows Users - Options:

a) After unpacking just doubleclick the change_layout_mtbmap.cmd it will ask you which layout to chose – and within 2-3 seconds it will be changed.

For the contourlines gmapsupp.img downloads run the change_layout_contourlines.cmd after unpacking. This way you can choose how dominant/thick/thin the contourlines are displayed. By default your device does this automatically – but you can change it to your liking this way.

b) You can also drag or drop any OpenMTBMap gmapsupp.img file directly onto the change_layout_mtbmap.cmd – that’s very useful if for example you want to change the layout of an openmtbmap gmapsupp.img file that is already on the mSD of your device. No need to move it back to your desktop. Just drop it onto the change_layout_mtbmap.cmd and the layout can be changed within seconds. 

Note 1: never drop a contourlines gmapsupp.img file onto the change_layout_mtbmap.cmd – else you will end up with a very strange looking map if the script/program runs at all.

Note 2: Never drop a gmapsupp.img file created with MapInstall or Mapsource onto the change_layout_mtbmap.cmd if it contains several different maps. In that case you will lose the layout for all but one map inside the gmapsupp.img container.

c) Advanced users only – run from cmd.exe terminal:

change_layout_mtbmap.cmd gmapsupp_Austria.img wide.TYP

The first argument is the name/location of the gmapsupp.img file, the second the .TYP-file . It’s easiest to just drag all three files after each other into the terminal. Note – if you want to pass a custom .TYP-file, you have to give the first argument about gmapsupp.img location too. You can also only pass

change_layout_mtbmap.cmd gmapsupp_Austria.img

 
Mac OSx and Linux users:

Note – not possible anymore with macOS v10.15 or newer. gmt_osx is 32bit only and the author does not plan to release a 64bit version.

Note – if you don’t open the terminal in the directory of the .sh file – then first go per “cd”

into the correct folder/directory – then

a) open terminal and run:

bash change_layout_mtbmap.sh

a1) instead of running the script via terminal – make it executable.

either via file properties or in terminal with:

chmod u+x change_layout_mtbmap.sh

Now you can start the script by doubleclick. You can also just drop a gmapsupp.img file in your file explorer/finder onto the script in order to change that gmapsupp.img layout.

The contourlines layout can be changed just the same way using the change_layout_contourlines_gmapsupp.sh script.

 

b) for advanced users – in terminal run:

bash change_layout_mtbmap.sh gmapsupp.img

or 

bash change_layout_mtbmap.sh gmapsupp.img wide.TYP

The first argument has to be the gmapsupp.img file – the optional second argument is the .TYP file (if you want to add a custom .TYP file)

Note 1: never drop a contourlines gmapsupp.img file onto the change_layout_mtbmap.sh – else you will end up with a very strange looking map if the script/program runs at all.

The contourlines layout can be changed just the same way using the change_layout_contourlines_gmapsupp.sh script.

Note 2: Never give a gmapsupp.img file created with MapInstall to change_layout_mtbmap.sh if it contains several different maps. In that case you will lose the layout for all but one map inside the gmapsupp.img container.

 

Map Visibility in Basecamp

By default I've disabled that maps are loaded for display/to show in Basecamp. However if you like to see the map when connecting the GPS device or mSD card to your computer with Basecamp open - you can run the change map layout script (see Adapting the Map Layout above) - at the end of the script you will be asked to enable or disable the Basecamp Map Visibility.

 

Joining gmapsupp.img files for very old devices 

 

Very old devices - Join gmapsupp.img files

Very old devices like etrex vista HCx or GPSMaps 60 CSx – can only use one map file – called gmapsupp.img (max size 4GB). Now if you would like several countries or map plus contourlines to show – you need to join the .img files first.

To do that – add the additional .img files (e.g. contours_austria.img) to the extracted folder of the map. Then run the script:

Combine_all_img_files_into_a_single_gmapsupp_img

 

On Windows you simply doubleclick the Combine_all_img_files_into_a_single_gmapsupp_img.cmd script.

 

on OSx or Linux you open the the .sh script from terminal by

bash Combine_all_img_files_into_a_single_gmapsupp_img.sh

(or chmod u+x to make it executable first, then run it by doubleclick).

Note – if you don’t open the terminal in the directory of the .sh file – then first go per “cd”

into the correct folder/directory.

Note -this is not possible anymore with macOS v10.15 or newer. gmt_osx is 32bit only and the author does not plan to release a 64bit version.

The following contourlines are with the standard recommended equidistance of 20m. In mountaineous regions I recommend to use 20m equidistance. However as of popular demand you can alternatively download 10m equidistance for all countries and continents (except Asia continent map - because it is too large). Note that the underlying data outside of Europe in mountaineous regions is actually not good enough to really profit from 10m equidistance lines at all. For flat regions however worldwide 10m contourlines can make sense. So that's why I offer them for download worldwide.

In general I recommend not to install more than 6-8GB of maps on your device at any time. As the contourlines do not have an address index or any POI they don't count towards that limit - as they will not slow down your device like normal maps do.

Do note however that all Garmin devices have a max tile limit of 2048 or 4096 - so do not forget about that. The South America contourlines 10m for example already have about 3000 tiles.  So better just export those ones that you need by using the windows or osX gmapi download instead and send with MapInstall. (that is alsow why there are not Asia gmapsupp 10m contourlines - they would break the 4096 tile limit.)

If you break the 2048 or 4096 tile limit - some tiles simply will not be shown - which ones I cannot tell you - that's random.  Be very careful about this limit if you go for the 10m contourlines for a continent - or if you insist to install the 20m Asia continent gmapsupp contourlines (also over 3000 tiles).

I cannot tell you for gmapsupp.img downloads consisting of several gmapsupp.img maps which map covers which part. That is a bit random too. You can look at the gmapsupp.img map coverage by loading them in QmapShack.

Also in Europe only where there is LIDAR coverage 10m contourlines make sense in mountain regions. Inside the copyright file you can find out the data sources.

    Hi Mike!
    I own an Garmin Oregon 750t, I tried the actual *.img in the Unicode-Version and they work fine. I thought I tell you this because of your remarks about this versions wouldn’t work with this device because of Garmin’s “philosophy- possibly they change mind or did I sth wrong 🧐 (SW-Version is 5.90).

    Thank you for your work from a longtime fan of your work!

    • extremecarver

      No they do not work at all. Mind many *.img listed in the Unicode section are just listed there for convenience. Only maps with _UC in their name are actually Unicode – and they are definitely not running on 750t series. Last compatible model was 600/650.

  • Mikebike

    Hi,
    I’ve purchased a Garmin 66SSr, downloaded and installed throught Basecamp the mtbItaly gmapsupp ( contourlines already integrated) and It works great, I Can even choose from different layout before uploading the map to the device.
    For my adventure, bike, hike….I use Oruxmap as well. I downloaded the gmapsupp map,the zip directly to install to garmin device, and installed it into the Oruxmap mapfolder. It works, but unfortunately, due to the fact that contourlines are not integrated into the file, map is without contourlines. Is there a way to add contourlines. Any suggestions?
    thanks

    • extremecarver

      If you are using windows – you can use the combine script that is part of the contourlines gmapsupp.img download. Otherwise you need to send the map with integrated contourlines to the phone (you will first need to send it to the /garmin folder on the phone – then move it to the Oruxmaps folder. You can also send it first to any external drive).
