Smooth contour lines

[utagawal]

In case you'd like to smooth contour lines here is a project that could be used : https://github.com/MathiasGroebe/Smooth-Contours

I have been using https://github.com/onthegomap/maplibre-contour with maplibre web maps, It uses the raster-dem and generates the contour lines on the fly, instead of pre-generating them.

I never was very happy with the lines my script here generated, so feel free to make a PR if you want to improve them.
