In ValValetl/SMMT: The Swiss Municipal Data Merger Tool Maps Municipalities Over Time

Swiss Municipality Data Merger Tool

Introduction

The SMMT is an R Package which helps merge municipal level data sets available for different points in time.

If you ever worked with Swiss municipal-level data, you almost certainly encountered the issue that the municipal state of your dataset is not the one you desired. E.g. it’s not the actual municpial state or it does not match the state of a second dataset.

This R package helps to bring the municipal states together.

A good starting point is this vignette article.

The Swiss Municipal Data Merger Tool automatically detects these mutations and maps municipalities over time, i.e. municipalities of an old state to municipalities of a new state. This functionality is helpful when working with datasets that are based on different spatial references like for example Swiss voting data.
