Features

• Interactive map interface based on @mapcomponents/react-maplibre
• Select regions of interest using a resizable, rotatable bounding box
• Generate 3D terrain models from digital elevation model (DEM) data
• Automatically include buildings with appropriate heights

• Preview 3D models directly in the browser
• Download models in OBJ format for use in other applications
