Thread: Help please on tile selection

Have a look at this program : load and edit every layer you like, then generate Raster/Vector/Geojson and a few others, this program is free and is a hi level GIS.
Enjoy.

It is Open source.

@Magnetron
Thanks for the suggestion.
I had QGis in my list of pending study matters. Quite steep learning curve. I have been unable to load (garmin) mapset IMGs into it.
Any indication is welcome!
(I am editing the original post to ensure that readers understand that I speak about Garmin IMGs and not image IMG nor disk image IMGs)

GpsMapEdit can adjust the zoom levels of maps/tiles.
But as already noted I think you have to convert to .mp, edit, then convert back to .img.
I use TypViewer to edit any .typ files, and replace them in the .img using GMapTool.

I'm not sure if there's any software out there that can do everything in the one program, possibly there is, but I don't know of any.

I tried to look @ .img but since the apps I use don't need that form of Encryption I forgot about it. Am not interested in modding a Navi unit. I only use TT NDS for fun coz as soon as I get bush they are useless. I use OziExplorer and Trilobite for serious off road work.


Hi JmaCWQ long time no see.

Thank you all!

@Butters, @Magnetron

My aim is not at all to tinker with garmin propietary protected maps. I am happy with the lifetime updates of CN I paid for, and I do not plan either to tinker with those IMGs.

My target is to use in my garmin those osm free maps in IMG mapset format, such as the ones provided in [Only registered and activated users can see links. ]

Besides eventually for my GPSrs, the most interesting use of the IMGs for me is to plan trips (for what I use user oriented open software that is able to use IMGs - other formats need more expertise). Editing maps (beyond chopping not needed areas and adjusting zoom) is not my interest, just a hassle in order to allow me the planning: for practical reasons I wish to have smaller size files just of the areas of interest for me. Lets say, for example, I wish just Ireland but not UK in the same file. So I wish to remove UK from the file. Or just the Loira river area and not full France. Sydney but not Adelaida. Algonquin Park but not full Ontario. Benin but not full Africa. Yosemite Park but not full California. You name it.

Tools go (MapEdit cannot load full size France IMG), go faster (CPU, RAM reasons), less Disk access and lower use of storage...

I am really surprised to find out that no tool seems available to do what I would like. Even to build up a toolchain with command based executables performing each one step. But starts to look that garmin IMG tinkering is passé, old knowledge forgotten, no further/new tools development that use it. There is not even a x64 version of MapEdit! (with big issues of RAM limitations) - seems there is no demand for Konstantin to take the effort. It seems a miracle that he keeps it updated and removing issues and adding some features.

@Butters

Tinkering with garmin maps (even purchased ones) is illegal in most countries, but others not (although usually restricted to own non-commercial fair use). Whatever is the case, I am not interested in that, but note that although illegal it can be done; same applies to GPSrs firmware.

GMaptool is the a) path that I indicated and the less un-efficient.

@JmaCWQ

So, can zoom levels be adjusted with a different TYP file?

TIA again,
CT

Hope you find something that does what your after,
Since the 2017 crash this is the ruling now prob the reason no one is doing such things your after on here.


Under Rule #9 here: [Only registered and activated users can see links. ]
9- BE RESPECTFUL OF THE LAW . This means no upload of any illegal activities, copyright infringement, or pirated intellectual property.

ALL Garmin and Tom Tom Maps that are uploaded will be removed and anybody that re-uploads a file that has been taken down will receive infractions for not following the rules.

@caspertone,

I do not understand why you are having problems. If you know anything about Garmin GPS units the easiest way to make any size map is to use "Garmin Mapsource".
In the example I show in the screen shot using an Openstreet map installed on my laptop. "Openstreet Belgium,Holland, Luxemburg and Germany.

Please note most openstreet maps come with an install version for your PC or a complele IMG file to copy to your GPS Unit.

In the PC installed version you can pick any area of the map you want and add as many tiles as you want and make a IMG of the area you need.

See screen shot:

Spoiler: How to pick map tiles you want.

I have picked 3 tiles as this example to compile into an IMG file to use on my Garmin GPS.

I have an arrow pointing to the tool you use to pick the tiles you want. Click on each till you and and they will show in the window to the left.
Then go to the menu again and pick "Transfer"

Spoiler: Transfer to GPS unit

Make sure you GPS Unit is attached to your PC......

Then click "Send to Device" it will then make the file "gmapsupp.img".

Make sure you do not have a file on your GPS already with the name "gmapsupp.img" rename it or copy it to your PC.

If you have a new GPS for hiking you can also give it a different name to reflect what map it is.
That also goes for the map you just transfers to you GPS via "Garmin Mapsource"

You can also do the same for any owned Garmin map that is installed on your PC that you paid for.

Remember you can only use Garmin Paid maps for your own personal use if you make map tiles from a commercial version you own and is install on your PC using "Garmin Mapsource"

We do this all the time when I take people out for the first time they every used a handheld GPS Unit.
I make a small openstreet maps of the area I am taking the group on. Each having a GPS unit I supply for them to use.
