Aerial & satellite imagery analysis

 
Our experts are among the UK's most experienced exponents in the analysis of aerial and satellite imagery. This material encompasses visible spectrum, infra-red and occasionally, radar imagery, each of which requires expert training.
 
Aerial and satellite imagery are most often used in boundary and land usage disputes, but when available, have been used to great effect in the past in criminal investigations, including missing person searches and clandestine grave detection.
 

Vertical imagery

Vertical imagery creates a plan view of the target area. Scale is constant in a true vertical and little, if any ground is hidden from the observer. Our experts can analyse such images, measure features and provide answers to innumerable questions.
 

Oblique imagery

Oblique imagery produces a more readily recognisable image, but a lot of detail is lost in areas behind the objects in the picture. Scaling and measurement is more complex, but the perspective is readily understood.
 

Monochrome imagery

Monochrome is historically a cheaper medium than colour and is also faster in terms of registering light returns on the film. Both factors, however, are becoming less relevant with the falling cost and improved quality of digital colour photography.
 

Colour imagery

Colour images provide more discernible detail because the human eye is more responsive to colour tones than it is to shades of grey.
 

False colour imagery

False colour imagery is sensitive to the near infra-red/visible band of the spectrum and is used primarily to monitor areas of vegetation. Healthy chlorophyll readily reflects infrared and this is recorded in red on the image. Unhealthy areas or those that are not actively growing shown as shades from red to brown.
