This model automates viewshed analysis in QGIS, converting raster output to vector polygons. GDAL is used for vieshed analysis. Originally used for optimizing IoT gateway placement, it includes input attributes like antenna height and building floors. The observer height is calculated as antenna height + (building floor count * 3), where floor height is fixed at 3 meters, making the model adaptable for urban visibility studies.

Features:

• Converts viewshed results to vector polygons.
• Retains input attributes like antenna and building floors.
• Observer height is calculated automatically through an expression.

Changelog: V2.2 * Output layers name shows the location name by using Load layers into project algorithm * Outputs are no longer grouped V2.1 * Changed [raster pixels to polygon] to Polygonize (GDAL)
