Affected Area Models

QGIS Processing Models
Per Project QGIS Modeler

Overview

Parameterised models that compute per-lot affected area along route corridors for acquisition and compensation planning, with supporting models for tower footprint boxes and lot outlines.

How it works

Two streams measure affected lot area, merge, and two supporting models feed in.
