The bottom line is: you cannot distribute Garmin maps made with the free / shareware or personal version of cgpsmapper if they contain OSM data. This is in conflict with the OSM license. Unfortunately the license for the free version of cgpsmapper states that the produced maps cannot be distributed for commercial purposes. GroundTruth uses 3rd party cgpsmapper software to generate the actual. Igor Brejc, the author of GroundTruth, also thinks that there’s an issue with publicly distributing maps created using Ground Truth. The last has kept me from trying it out the requirement to set map data and parameters using command-line options, outlined in the wiki GroundTruth manual, is a bit more effort than I’m willing to put in.

Automatic uploading of generated maps onto a GPS unit.

Registration of generated maps into Mapsource.

Conversion of national characters into the ones supported by Garmin units.

Remove 4 band with gdal_translate gdal_translate -b 1 -b 2 -b 3 input.tif output.Continued from the last post, a few more tools for creating Garmin vector maps using OpenStreetMap data these are more comprehensive map creation programs. When you create tiles the script above creates 4 band jpegs which are displayed properly in Google Earth but make Garmin go haywire.

QGIS adds a fourth band to the exported geotiff. My only 'inkling' has to do with colorspace - the individual jpeg files in the kml have a different hue than both the geotiff and the kmz displayed in Google Earth. kmz is detected by the GPS unit and correctly placed, but no images are displayed. kmz displays just fine in Google Earth and I have used the same process before to make some maps for a friend with success.įor some reason the. tile number (<100 / 500 in case of my GPSMaps64S) In theory and from what I can tell in practice, these scripts take care of the Garmin limitations: I then convert it into kmz using scripts from this GitHub repo: I have created my own map in QGIS, exported it to a georeferenced, ~5m resolution, EPSG:4326 geotiff. I'm at my wits end and would really appreciate any suggestions.
