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:

But this is slow. It would be much better to have an option for that.

Thanks

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

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
