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

[Sebastian Gutwein]

Just so you know all your options :). There is also the Whitebox Tools
plugin for QGIS (you need to install whitebox tools) that has a
NaturalNeighourInterpolation algo. "Creates a raster grid based on Sibson's
natural neighbour method"
