The following is a model of Inner Mongolia Autonomous Region of China, which uses geojson format to draw the surface, but does not see the drawn surface in the corresponding area. How to solve this problem? There are many ways to convert the longitude and latitude to correspond to x and y in the community, but they are all for the whole earth
Your imported mesh is not in the same coordinates as produced by sphericalToCartesian. I scaled and centered polygon to be visible, but you’ll need to fix this to match the imported coordinates to the polygon coordinates.
