Re: [Qgis-user] How to replicate ARC-GIS Natural Neighbour Interpolation Algorithm in QGIS / DTM from elevation points

If your'e willing to try GRASS GIS, then the module v.surf.nnbathy should help.

Hi, I’m building a DTM from random points (with different distances in between) and I like ArcGIS Natural Neighbour algorithm for doing so.

Is there any way to replicate it in QGIS? https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-natural-neighbor-works.htm

Alternatively, what would be a way to constructing DTM from points, preserving the original points in respective pixels?

Thank you!
