This plugin takes a line-based network and point-based origin layer and calculated the distance from each segment within a given radius to each of the origins. The tool outputs the catchment as lines and as a concave hull polygon layer.
The plug-in can be installed from the QGIS Plugins Manager, and updates become automatically available once submitted to the QGIS plugins repository.
