Aerial photos show the buried archaeological features. Clear indications can be seen in the crops of settlement enclosures, trackways, pits, ring ditches (possible Bronze Age barrows) and natural features. All these features are masked in places by areas of deeper soil.

Air photo interpretation differentiates the archaeological and natural features.

The interpreted photo was ortho-rectified to fit a scaled OS map base.

Aerial Photographic Assessment of an Iron-Age & Romano-British settlement
Fenstanton, Cambridgeshire

This site is a complex Iron Age settlement, which shows up as marks in growing crops, where the plants grow stronger and greener over buried ditches and areas of deeper soil.

This site is totally invisible on the ground.

To allow archaeological investigations to be targeted effectively and accurately, the oblique aerial photos must be interpreted, and rectified to fit an Ordnance Survey map base.
