New publication: Introducing the vectorial Kappa: an index to quantify congruence between vectorial mosaics


With Mathieu Castets, Jules Morel and Cédric Gaucherel, we extended Cohen’s Kappa to directly calculate the Kappa index between two vectorial landscapes.

We thus:

  1. skip the rasterization step
  2. obtain the exact Kappa.

This short paper have been published in Ecological Indicators.

It comes with an R package and a Java utility. Code + softs are available on my GitHub page and detailed here.
