AreaInterpolation

AreaInterpolation.jl is a package to perform "areal interpolation", that is, interpolating values associated with one set of polygons, to another set of polygons that overlap the first set ¹.

Similar implementations in other languages can be found in ² (R), ³ (R), and ⁴ (Python).

Quick start

The main entry point is the AreaInterpolation.interpolate([alg], source, dest; extensive = (:col_a, :col_b), intensive = (:col1, :col2)).

Performance

AreaInterpolation.jl offers seamless multithreading support, and integrates with the rest of the Julia ecosystem as well!
