Aerial Line Photography
A line survey is a continuous photographic sweep over a significant distance - such as a pipeline, power line or coastline. This type of survey can be conducted using either oblique or vertical photography, at high or low altitude.
The aerial line photography service is extensively used to monitor gas and oil pipelines for planning construction and future defence. Line Surveys are also widely used to monitor and plan for errosion control on coastlines and rivers. Such work involves photographing at regular intervals of say 1km, with a slight overlap at either side for continuation.
Air Images are hugely experienced in this specialist field and offer the complete package from detailed planning, to capturing the highest quality aerial line photography, right through to digital presentation and photogrammetry.
Again, we only use the highest quality equipment - either medium format or digital cameras, for our line survey work, which is then supplied to the client in digital and / or print form. All imagery provided can be cross referenced with GPS derived mapping data - either Ordnance Survey grid reference or latitude and longitude, date, time and altitude of each image can also be stamped.
The images below are a section of a vast aerial line photography survey to photograph an underground pipeline route. The photographs are taken in scaled segments to show a specific area of interest either side of the line.
The photographs can then be mosaiced together to produce a larger section:
