About these reports
Topographical survey. A topographical survey measures the exact shape, levels and features of your site, and is usually the first thing an architect or designer needs before drawing up plans, especially on sloping ground or where levels matter to the design.
Drone survey. A drone survey uses a small unmanned aircraft (a drone, or UAV) to photograph, film or measure a roof, building or site from the air.
