GLOSSARY / Assessment & research

Historical aerial photography

Aerial images captured at an earlier date, used to investigate previous land use, development and visible changes across a site.

THE RRS GLOSSARY

Why it matters to a project

Image dates, resolution and interpretation limits matter. A photograph can add context but should be considered as one part of a wider evidence base.

PROJECT EXAMPLE

Images from different periods are compared to understand redevelopment after wartime activity.

A useful distinction

An image showing an apparently clear surface does not establish what remains below ground.
