Screenshots (Desktop)



Just a collection of screenshots from Basecamp and Mapsource to give you an image on how the map looks like on your desktop. (note while you can choose to use the same layout on your GPS, it is recommended to use one of the 3 GPS layouts with higher contrast as they are easier to read with bad light conditions):


Note that the openmtbmap is a vector map that is drawn realtime on your PC/GPS. While raster maps are handdrawn and you would need one map for every resolution, vector maps are drawn realtime by your GPS/PC. This means that things like labels or density of streets/ways may be too much or too low. On the other hand vector maps are fully scalable, freely zoomable, rotatable (without letters being drawn upsidedown), autorouting capable, searchable, ....  But hey, as you can see on the screenshots, the rendering quality is not far off from raster maps!


Following is a series of zooming into Germany Hamburg (1. shot: detail resolution from infinite to 70km)






(3-2km resolution)

(1.5-1km resolution)


Note the following screenshot highlight too much information shown (the labels are not wisely chosen and interfere a bit) (700-300m resolution). But hey, on the zooming in phase this is basically the only one that is suboptimal.


This is the highest detail level (200m to 20m resolution). Note you can still zoom in closer without quality degradation of course. Only there is no more additional information showing up.

    Hier sind 2 Screenshots von openmtbmap (gmapsupp.img). Mit dem Programm QMapShack auf ein Linux-System (Ubuntu 20.04). Läuft gut 😉

    I installed the Canary islands map on 31-10. As I have a garmin etrex 30x I installed the non unicode map for my mac. In comparison to the old map it shows grey 3d contours. Is it possible to switch that off? I choose the hiking layout and integrated the contour lines. See attachment.

    thanks for your help and best regards, Els

      On your device you can switch it off. In Basecamp there is no way to do so

      You could strip the DEM data using gmaptool. It’s actually not very complicated. However you will have to use the command line version as there is no graphical version unter Mac OSx
      1. Drag all 7*.img files into gmaptool window.
      2. Create a new subfolder called no_dem
      2. On the Join Tab – select a new output name in the no_dem folder. E.g. nodem.img. Select the “Remove altitude data DEM”. Confirm with Join All.
      3. Now go back to the Files tab – delete the 7*.img files – and drag in instead the newly created nodem.img from step 2.
      4. Go to the split tab – Untick the “Compile Preview Map” option – as we do not need it. Select again the new folder created in step 2. Confirm with Split selected.
      5. Now take all the newly splitted 7*.img files from the no_dem folder – and overwrite the 7*.img files from the main map folder.
      6. Your finished – don’t forget to delete the Basecamp cache by pressing CTRL-G twice in Windows.
      6. OS x: to delete Basecamp cache – clear:
      ~ being your home folder.

      You can do this from Terminal using the command /bin/rm -r ~/Library/Caches/com.garmin.BaseCamp/TileCache/*

      it’s also possible that the Tilecache is located here:

      basically the commands are:
      gmt -j -o nodem957.img -q 7*.img
      gmt-S nodem957.img
      the overwrite the old 7*.img files with the new ones.

      I hope to add a bash script to the next map update to do this automatically. For windows the script is already written – for mac os and linux I still have to do it.

      okay – well my last 2 comments were useless – because the file structure is so different for gmap style maps. But actually it’s even easier – you just need to delete/remove the DEM files in the 7* folders under Mac OS x – I’ve included a script that can disable/re-enable the DEM. It will come for all maps on next map update – and I just uploaded Canary islands so you can try it out. Just right click on – make it executable – and you can disable all the DEM files. Please post back if something doesn’t work – I’ve only tested it on linux (but bash and commands are very similar – so I am pretty sure it runs just fine on OS x).
