scattered-data

High-order interpolation, differentiation, integration and smoothing on discrete samples in arbitrary dimensions.

Fast continent-scale raster interpolation for scattered point data. Turns millions of geolocated points into gapless GeoTIFF in minutes using IDW and pull-push mipmap algorithms. No GPU required.

A Python implementation of the Faul-Goodsen-Powell algorithm for multidimensional interpolation with radial basis functions.

Gradient, divergence, curl and Laplacian of scalar, vector and tensor fields on scattered points, second-order accurate and mesh-free.
