Scaling issue

[RodrigoHamuy]

Do we know why scaling seems to be quite off?

I took the Chaillot data points from https://rodrigohamuy.github.io/react-three-map/?source=true&story=extrude-coordinates--extrude-coordinates#ladle_loc_13

Hello

This is expected from the deformation in the tiles projection

We could implement a strategy to fix deformation maybe by resizing the map based on where we are looking at or similar

@tentone , In the meantime we are using import { pointToTile, tileToBBOX } from "@mapbox/tilebelt"; to set the root node to fix scaling, if it helps for inspiration.

But if there is a nicer solution in the future that would be great.

This would be a good solution for the issue, scaling based on the map point.

I think that we should move this code into a separate util that can be attached to the map instance.

I'm trying very hard to make the map work in my project with the correct scale. In my case i don't want to change the map position, but move the camera to the correct coordinates of the map instead. Is it possible?

Also the scaling and positioning seems very confusing: setting the map to map.scale.set(0.01, 0.01, 0.01);

map is too small, so i set the scale to 1000 and its visible

I try UnitsUtils.datumsToSpherical(lat, lng); and set the r3f MapControls to the position and target position but the vector3 values are thousands and it positions the camera very far away from the map.

@tentone can you give a bit more details on how these scaling and positions work?
