Hi wp\_newbie! Welcome to our community 🙂

The PreEA tool provides a user-friendly workflow within the open-source QGIS platform, making it more accessible for national statistical offices that may not have access to commercial software. The tool also aligns boundaries with visible ground features such as roads and waterways.
