Via Michelin maps - possible to add to Locus?

[barbudor]

Hi

I've tried the above BSH script in MoBAC.
While it seems to get tiles down to zoom 10, the position is totally wrong.
For example zooming out from one position move totally out.

As anyone made some progress on this one ?

Hi all (well, seems not so many persons interested... anyway).

Very nice job you've done, "2012".

So we are able to identify all ViaMich tiles.
But to use them, we need to geolocalize them.

How can we figure the position of tiles ? Either as Google XYZ or lat/lon ?

Hi.
They changed their tiling scheme some time ago, so you can easily integrate it into Locus.
Just create a new xml file (e. g.  michelin.xml) in the \Locus\mapsOnline\custom\ folder with the following content:

<?xml version="1.0" encoding="UTF-8" ?>
<!-- ViaMichelin maps -->
<providers>
<provider id="80118" type="0" visible="true" background="-1">
      <name>ViaMichelin</name>
      <mode>Michelin</mode>

      <url><![CDATA[http://map{s}.viamichelin.com/map/mapdirect?map=viamichelin&z={z}&x={x}&y={y}&format=png&version=201503191157&layer=background&locale=default&debug_pattern=.*]]></url>

Works great, many thanks!

When zooming in on the map on the viamichelin.com website, you might have noticed that around zoomlevel 11 on the bottom right side of the screen appears a clickable 'Michelin map' (and Bibendum head) box.
Clicking that opens another window and you will see or find the 'classic' Michelin map of 1:1.000.000 on the following address (in this example for the Malaga area):

https://www.viamichelin.com/1.85.0/html/michelinmap.html?lat=36.70682496124855&lon=-4.438819885253907&zoom=11&headerLabel=Maps%20%26%20Route%20Planner&apiJsConfigUrl=%2Fapijs%2F1.23.0%2Fapi%2Fjs%3Fkey%3DJSBS20110216111214120400892678%24166489%26lang%3Deng%26protocol%3Dhttps

Is it possible to add this to Locus and if so what would be the map source or .xml file for that map?

Thanks in advance for your kind help and suggestions!

Cheers,

@J3rry,

I think it´s not possible.
The tile url looks like

Code Select Expand

https://m11.viamichelin.com/mapsgene/dm/mapdirect;ZXVyX2NfMDAyNGtfcjA4;MDAwMDAwMjQwMTAwMDAwMDE0ODQ=?&protocol=https

Locus can handle only tile servers with a structure like z=? x=? y=? or this in an other order.

I haven't looked at this in many years. It's cool seeing what you guys have done since then.

I think the map/tiles that j3rry would like to see is the one I originally set out to try and get into Locus, and all the early posts (from way back in 2012) of this thread are about how to access those tiles properly.
I also think, like jusc, that Locus (still) does not have the capability to handle this type of tile URLs directly. The script for Mobac by Nicolas P seems very nice, I have not tested it.

I still wish we could handle this in Locus, and with proper geo-alignment. It would be very nice if Locus could support some kind of user scripts to handle this type of issues, and we could seamlessly integrate many more tile servers.

[2012]

If you think user scripts for this purpose would be interesting, you can take a look at this idea I added to Locus Help Desk (and vote for it if you like):
