Elevation sampler not the same with custom elevation input

Hi,

I'm initializing initial input into ElevationProfile. However, the line generated from the sampler seems like having an offset from the initial input. Any idea why?

Your polyline is very long but only has a few points.  For better display and analytical results, try to densify the polyline before creating a profile.  https://codepen.io/john-grayson/pen/NWwaoBg

Thanks @JohnGrayson . By the way, as we zoom in the line will eventually having offset, is it because of the demResolution?
