# mapbox-elevation

A script to convert mapbox elevation tiles into grayscale heightmaps.  

[Demo clip](demo.mp4)

Various tools like [Blender](https://www.blender.org/) support generating meshes

from grayscale heightmaps. Mapbox provides an API to access heightmaps, but

uses a different format to encode the heights in order to allow for higher 

resolution in the elevation values. 

When run with a local webserver, this program will take the file named

`heightmap.png` (from the Mapbox API) and create a grayscale version

using the Javascript Canvas API. The output in the Canvas can be saved

as a new image.
