GPSr Units / Re: Best big screen GPS for custom maps

I doubt if it is really compatible with topo maps. There is no offer for topo maps outside US. I guess it works like any other nuvi and you probably won't see POIs on map.

Different units show different info. It could be map name from img header or MPS subfile, copyright from TRE subfile, license from LBL subfile. Garmin maps in GMP format contain some additional legal warning, which I have never seen presented in GPS.

For cgpsmapper copyright is fixed but you can set own license text. For mkgmap you can set copyright and license. Map names in img can be edited by GMapTool.

It is very new, one can expect some problems, but it works. I have published maps of Africa and South America with DEM. They become big.

BuildDEMFile creates subfile DEM based on given area or area extracted from subfile TRE (subfile as an internal part of an img tile). It is quite tricky to add DEM to existing map, but can be done with gmaptool.

Mkgmap is is easy. Just put some option like required resolution and path to SRTM files. Then mkgmap adds DEM to each tile. Actually I haven't tried with *.mp source, but with OSM data, maps compile without problems.

Garmin's 24k topo maps include DEM (Digital Elevation Model) data in their proprietary format that provides 3d shaded terrain. This feature is only available on Garmin products, there are no third party tools for using DEM in a map.
This is no longer true, mkgmap and BuildDEMFile can create DEM now. See:

Hi Brian,

you could try my maps of Asia, based on OSM data:

There is no clear rule, it depends on GPS. See some info here:

Using The Maps/Garmin Software / Re: FontStyle= for lines in .TYP file

I think there should be 2 lines, like:


Try to use some TYP editor, I recommend TypViewr:

Routable means, that map supports routing. A suitable GPS can trace a path between 2 points, which uses roads from the map. When map is not routable, GPS will use straight lines instead (well, probably great circle path).

Address search is a separate functionality, where GPS can convert street address into geographic location.

While maps created by Garmin usually include both features, this is not necessary the case for free maps, where creators often lack mapping data or programs to create fully functional map.

BaseCamp is a convenient tool to manage maps. You can easy transfer maps from BaseCamp to GPS but there is no perfect way to do opposite - transfer maps from GPS to PC. People usually want to use maps on both devices, so  IMHO better to offer maps for BaseCamp than a file for GPS.

Well, it's not all automatic, but I offer the same download for Windows and Mac.

I assume that you are using Window 7 or newer. I hope that you have already installed 7-zip. If not, please download it and install, its site is here:

Using Windows Explorer, find downloaded map archive on your HDD and right-click on it. You should see pop-up menu, which include some commands added by 7-zip. Use 7-Zip -> Extract files. This will open a window with some options. Please select destination directory (folder) on your HDD, you can use button "[...]" next to field "Extract to". You can create new directory if necessary. Then click "OK" and archive should be unpacked to selected directory.

Next navigate with Windows Explorer to previously selected directory and enter a subdirectory with a name like the map. You should find there files named like "install_US_South_Atlantic_OSM_Topo.bat" or install_US_South_Central_OSM_Topo.bat, depending on a map. Extension ".bat" could be invisible, it depends on settings of Windows Explorer. Files should have description like "batch file" (I'm not sure, how it is presented in English version). Double click at this file to execute it and map should be installed for BaseCamp.

I hope you know BaseCamp, it is a free program from Garmin. BaseCamp can be downloaded from here:

With BaseCamp you can browse map, design routes, collect POI etc. And you can install maps to your GPS. see this guide:

Yes, maps are routable and search for address should work.

Map can be routable but still without search index. Which one have you installed?

Are you currently in Europe? Please make sure, that your current location as shown by GPS is inside area of the map, that you are testing. If necessary you can fake position - switch GPS into demo mode (system menu - GPS), move map view to map area, find a POI or mark a point there, click it, select form point menu "Go" and then "Move to location". This is a procedure form Dakota, I hope Oregon works similarly.

When on map area, try to search for address.

However, long term I'm trying to decide if qGIS can meet my needs since it is free open source and looks pretty good. Pretty sure it can easily re-project too.
QGIS is a very useful program but a bit buggy. It can reproject maps.

Other tools for this task are command line tools like GDAL. It is bundled with QGIS distribution, so the easiest way to get this working is to install QGIS.

Reprojection is only relevant to Raster data as Vector data has no associated projection.
All Garmin maps are WGS84, but vector data in general do have projection, which should be converted to WGS84 for creating maps for Garmin.

Now in the past, I think Garmin's software would apply elevations from wherever your track/route crossed an elevation contour on a regular topo map. Not sure if that system is still supported on their newer software and devices.
It still works in BaseCamp.

The number of objects for GPSMapEdit is limited by available memory, which is about 2GB for 32-bit executable. I think it is still more than could be contained in a single img tile.

Does your layers contain specific object types? Like for example one layer with parcels and second layer with buildings, where you want buildings to be drawn over parcels?

In this case, loading shp layers into GPSMapEdit merges all data into single layer. You have no direct control, which objects are drawn on top. To make your map look correct in GPS, you should design a TYP file, which contains graphics properties of objects including draw order for different area types.
