Above All Images has vast experience in the provision of Gas Pipeline TD1 studies. This imagery is taken vertically over the length of the buried pipeline across a width of around 400m. The photography is over-lapped to provide a continuous image along the pipeline which shows all surface features, vegetation ingress and man-made events such as un-authorised building or any other actions likely to interfere with the pipeline.
Since the pipeline is buried and not visible from the aircraft, we fly the survey using precisely plotted flight lines. All imagery is provided with GPS data together with a spreadsheet that links images to mapping to allow easy interrogation of the imagery. All photography can also be provided ‘North Up’ to allow easy map comparison.
