[mkgmap-dev] [Patch] set map-version in img header

Tue Jan 17 19:26:02 GMT 2017

Hi Gerd,

I could not test it on my GPS, yet. But your option works well for my map on Homeport.

I set option
--map-version=17.01
and Homeport shows v17.01
GMapTool also reports correct version:

Datei:		G:/garmin/gmapsupp.img, Länge 1940029440
Header:   	17.01.2017 18:09:28, DSKIMG, XOR 00, V 17.01, Ms 0
Mapset:   	OpenSeaMap_EuCentral
Fat:		400h - 600h - 80000h, Block 32768
Maps:		322, Subdateien 962

One more question:

Could your perhaps also implement an option
--marine
to set marine header?

Currently I have to patch headers using this tool:
https://github.com/OpenSeaMap/garmin/tree/master/gmarine
But this is slow. It would be much better to have an option for that.

Thanks

Hi all,

the attached patch implements new option map-version:
--map-version=major.minor
	The map version is written into the header of each *.img file
	at offset 8 and 9. Defailt is 0.0. Both major and minor values must be
	between 0 and 255 (including).
	Example: --map-version=1.7 (same  as --map-version=01.07)

A binary based on r3753 is here:

I seem to have no Garmin software that displays this version, so I don't 
know for sure what the meaning is. Please suggest better option name or
description if you know more.

Gerd
