What is a viewshed analysis?

Short answer

A Viewshed Analysis shows where a development is visible from surrounding areas. It helps assess visual impact and supports planning applications where sightlines and visibility matter.

Full answer

A Viewshed Analysis uses mapping and elevation data to identify where your proposed development can be seen from. It considers landform, vegetation and buildings to model sightlines from public and private viewpoints. Councils often request this analysis when a building is near sensitive areas like parklands, ridgelines or heritage zones. The report helps assess how visible the project will be and whether it will change the visual character of an area.

Why this matters

Many DAs are refused or delayed due to poor management of visual impact. A Viewshed Analysis can help avoid objections by showing how your design respects surrounding views and landscape values.
