Comment avoir la couche ''Mapterhorn'' pour le relief ?

Bonjour à toutes et tous.

Depuis des années, j'utilise Locus Map en rando et en VTT, avec les cartes OpenAndroMaps et j'en suis très satisfait.

Mais depuis peu j'ai découvert le site gpx.studio
Celui-ci utilise une surcouche ''Mapterhorn'' qui fait apparaître admirablement les reliefs. Ce ne sont plus de simple zones grises plus ou moins foncées. On a véritablement l'impression de voir les rochers sur la carte !

Avec mes peu de connaissances, j'ai cherché, mais je n'ai pas trouvé de moyen pour intégrer cette surcouche dans Locus Map.

D'où mes questions :
1) Y a t il moyen de l'intégrer en surcouche dans Locus Maps ?
2) Si oui, existe t il un tuto pour le faire ?
3) Si on ne peut pas l'intégrer sous forme de surcouche, peut on l'intégrer directement sur les cartes OpenMaps ?
4) ... Si oui, y a t il un tuto ?
5) Y a t il un espoir d'avoir cette surcouche intégrée sur les cartes Lomaps ? (téléphone et webappli)

Voici la comparaison entre les cartes Lomaps et gpx.studio à une échelle de 100m et 50m, sur une zone qui est une grosse colline et pas une montagne !

En vous remerciant de vos réponses.

Hello everyone,

For years, I have been using Locus Map for hiking and mountain biking, along with OpenAndroMaps, and I am very satisfied with them.

But recently, I discovered the website gpx.studio.
It uses a 'Mapterhorn' overlay that displays terrains and relief beautifully. They aren't just simple grey areas with varying shades anymore. You truly get the impression of seeing the actual rocks on the map!

With my limited knowledge, I've looked around but haven't found a way to integrate this overlay into Locus Map.

Hence my questions:

Is there a way to integrate it as an overlay in Locus Map?

If so, is there a tutorial on how to do it?

If it can't be integrated as an overlay, can it be integrated directly into OpenMaps?

... If so, is there a tutorial for that?

Is there any hope of getting this overlay integrated into Lomaps (both mobile and web app)?

Here is a comparison between Lomaps and gpx.studio at a 100m and 50m scale, covering an area that is just a large hill, not even a mountain!

Thank you in advance for your answers.

Hi Hudsson

Interesting photos, I downloaded the map and the theme, but haven't found the overlay. Where did you found it?

[hudsson]

Hi Joska.
You can go here : https://gpx.studio
On the right, you choose "Surcouche / Mapterhorn Relief"

I found this : https://mapterhorn.com

But I don't know how use it on Locus Map 

[Joska]

Could you post a screenshot, I dont find it

[hudsson]

You don't find what ?

[Joska]

I can not find the information, you've shown on your pics.

@hudsson
thank you for your message and for the detailed comparison - and also for being a long‑time Locus Map user :-)

We have actually started using Mapterhorn data as well in our web planner https://web.locusmap.app
However, we simplify the data quite heavily, because of data size, server load and bandwidth requirements. This is the main reason why the rendering in Locus Map currently looks less detailed than in gpx.studio.
But we do not rule out using a more detailed version in the future.

Regarding integration on your side:

Can raw Mapterhorn data be imported directly into Locus Map?
Unfortunately no - the raw data downloaded from Mapterhorn cannot be used directly in Locus Map.
They must first be converted into one of the supported formats:

• HGT (elevation grid)
• or a raster map (e.g., GeoTIFF → MBTiles)

For both alternative, you can use tools such as: Rasterio, GDAL

However, both require some work with the command line and basic knowledge of geodata processing. So I'm  not sure if suitable for you.

@Joska
You can't find the option because you haven't expanded the 'overlay' section.

@Voldapet
Thank you for your reply.
I look forward with hope to the day when the terrain shading can be used to its full potential.
Indeed, my level of knowledge in this area is currently limited and will certainly prevent me from doing it myself... but well, I'm going to try to explore. That's how we make progress!

In the meantime, I must admit I try other apps for my hikes and mountain biking, but I always give up very quickly to stick with Locus Map, which I find to be the most comprehensive.

Kudos to your whole team for your work.

@Hudsson
Yes, it looks in the pictures as if I hadn't opened the overlay section, but that's because I couldn't post the third picture with that section open. I'll go back and do that now, but I still can't find the overlay you described.

[hudsson]

Yes, I found the problem!
First, you must go to "Settings" at the top of the screen, and then to "Map Layers", where you can choose all the options that you want to use.

[Joska]

Did so, but altough checked, this layer is not to use.

[hudsson]

You haven't chosen the right option! 

I don't speak english very well... and less german    so, i'll use Gemini to translate
Tell me if it's good for you now.

Sie müssen in der oberen Leiste auf "Einstellungen" klicken, dann auf "Kartenebenen".
Öffnen Sie dann im rechten Fenster das Menü "Ebenenauswahi".
Dort können Sie im Untermenü "Basiskarte" alle Kartenformate ankreuzen, die Sie verwenden möchten, und im Untermenü "Ebenen" heißt die Option, die Sie interessiert und über die wir sprechen, "MapTiler Hillshade".

Wenn Sie nun auf der Karte sind und das rechte Menü benutzen, sollten Sie alle Karten auswählen können, die Sie oben markiert haben, sowie die Option "MapTiler Hillshade" aktivieren können (die auf Englisch und Französisch "Mapterhorn" heißt).

Ehrlich gesagt, Deutsch ist schon eine komische Sprache... wir sollten alle Französisch sprechen, das wäre viel einfacher !!!! Ich scherze natürlich.

Sagen Sie mir Bescheid, ob es dieses Mal bei Ihnen funktioniert.

Danke für deine Bemühungen. Ich bin ein älterer Nutzer, und nach vielen Versuchen habe ich angefangen an meinen Verstand zu zweifeln, denn grundsätzlich sind mit die Strategien klar, aber dann plötzlich, nachdem ich diverse Kombinationen von Karten und Ebenen ausprobiert habe, tauchte auf einmal MAPTERHORN rechts in den Auswahlmöglichkeiten auf. Interessante Darstellung.
Dann habe ich ein Häkchen testweise geändert, und Zack, MAPTERHORN verschwand, und es gelingt mir nicht mehr, diese Ebene hervor zu holen. Nach vielen Versuchen ist dann irgendwann auch gar keine Kartenauswahl mehr möglich, da scheint die Web-App noch etwas buggy.
Somit weiß ich jetzt, MAPTERHORN existiert, ist nur irgendwo wunderbar versteckt :-)

Thanks for your efforts. I'm an older user, and after many attempts, I started to doubt my own judgment, because I generally understand the strategies, but then suddenly, after trying out various combinations of cards and levels, MAPTERHORN suddenly appeared on the right among the options. Interesting presentation.
Then I changed a checkbox just to test it, and boom—MAPTERHORN disappeared, and now I can't bring that level back up. After many attempts, at some point I couldn't select any maps at all—the web app still seems a bit buggy.
So now I know that MAPTERHORN exists; it's just wonderfully hidden somewhere :-)
