Hi Felix

Forgive me if I’m a bit slow but

I can see the copyright and mapnumber,65310014 etc but where is the actual reference to the mkgmap’s version number?

Was it say compiled using 2179,2370 or non of these?

Even with the latest version of gmaptool I can’t see it .

If you use gmaptool, and click on details, then you would see it...

e.g. a sample output (makes me remember to change the sourcecode attribution from ccbysa to odbl..., something that should be done in trunk too...):

Maybe you find "Map created with mkgmap-svn" or "Map created with mkgmap-unknown". I think that happened when building from source on a windows machine, don't know it that is fixed now.

Thanks for your advise.

I’m looking at the raw data using my own software to parse the TRE ,RGN,LBL NOD MDR etc of an img

As far as I can tell there is no reference to mkgmaps’s version number , ie 2179,2370 in the img file itself.

By difference I meant looking at the contents/order of maplevels & subfiles in TRE or the POIS found in MDR4 using the same osm but different versions of mkgmap

Currently, I’m encountering some very strange & alarming behaviour when the gpx of a route disappears when zooming in .This only happens when I don’t need splitter.
I’ve never encounted the priority of an img override that of an IMG

Hmm, you should find the string Map created with mkgmap-rxxxx in the *.img file.
Don't you?

What tool do you use to compare two img files? If you just compare the files, you
will see a lot of differences even if you use the same mkgmap and the same input.
My identical_output_v2.patch might help, but one has to adapt it to current mkgmap releases.
