LiDAR survey

LiDAR stands for Light Detection and Ranging, and is a surveying technique that provides very accurate, high resolution 3D data. This survey has been undertaken on behalf of the project by the Environment Agency.

LiDAR is useful for many things in the field of archaeology, such as locating archaeological sites in dense undergrowth and beneath otherwise impenetrable forest canopies. Although Under Whitle isn’t known for its forests, LiDAR can also help distinguish features that are otherwise difficult to discern using other methods. In addition, it can cover a much larger area than can, say, geophysics.

Below is a map of the area that is covered by the LiDAR survey (the area is that defined by the red line).

We have received the data from the Environment Agency and various individuals involved in the project have been having a look, and a multitude of interesting archaeological features have been revealed – not only those we can investigate further at Under Whitle but also across a wide area of the parish of Sheen – just look at the map above to see what has been included (if you click on it, the image will open in a new window so that you can see it better).

Using LiDAR is also helping to confirm results of the geophysical and tape and offset surveys, and allowing us to compare and contrast the different methods.
