Ecological distance is a useful measure for assessing differences between e.g. two maps of the same area. This repository contains measures of ecological distance between NiN types, as well as scripts and source files for reproducing the calculations. See Documentation.md for an explanation of what ED is, and how it is calculated.
Ecological distance estimation and documentation for NiN version 2 is stored under /NiN_version_2. The rest of the repository is for NiN version 3. Note that NiN version 2 and 3 differ in many aspects, including the number of types (and mapping units), and ED is calculated in different ways. ED between the two versions should therefore not be compared directly.

Ecological distance, as defined in this repository, is based on the structure of the "Nature in Norway" system. The method further develops the concept and estimation of ecological distance from Eriksen et al. (2019) and Naas et al. (2023).
