GeoJSON Processing

This project demonstrates how to process and visualize GeoJSON data using Python. The input file used is open_adm_kommunegraenser_view.json, which contains geographical boundaries.

Code Overview

The code performs the following steps:

1. Loads the GeoJSON file using GeoPandas.
2. Sets the active geometry column.
3. Ensures the coordinate reference system (CRS) is set to EPSG:25832.
4. Plots the geographical data.
5. Plots the centroids of the geometries in red and saves the output as polygon_centroids.png.

Output

The output of the code is a PNG file showing the geographical boundaries with centroids marked in red.
