I updated the ZoomToBelgium plugin for QGIS to version v2.2.0. The plugin now also contains the location of the new Belgian municipalities that will be created at the beginning of 2025, because of the merger of multiple existing municipalities.
ZoomtoBelgium is a QGIS plugin the adds a button to zoom to any of the Belgian administrative boundaries (country, region, community, province, municipality or district).
