LIDAR images of Tintinhull area.

Lidar (Light detection and ranging) technology uses laser distance measuring technology to conduct topographic mapping.The LIDAR system measures distances directly from the aircraft to the ground during flight, using laser ranging. LIDAR has many applications in the field of archaeology including aiding in the planning of field campaigns, mapping features beneath forest canopy and providing an overview of broad, continuous features that may be indistinguishable on the ground. LIDAR can also provide archaeologists with the ability to create high-resolution digital elevation models (DEMs) of archaeological sites that can reveal micro-topography that are otherwise hidden by vegetation.

TLHG purchased the LIDAR tiles originally produced by The Environment Agency which cover some of the area around around the village. These were processed using the open source software, LandSerf to reveal surface features of archeological interest. We were particularly interested in the spread bank which we had found when doing a survey of the medieval ridge and furrow in the West Field and comparison with the LIDAR images. .

The processed images clearly show the presence of an archaeological feature which closely follows the outline determined in the landscape survey.

With more extreme processing of the lower tile, the ridge and furrow can be seen to overlay the bank as indicated in the next image. It should be noted that there appears to be a further linear feature to the right of the bank (with the dot at its lower end) which is also overlain by the ridge and furrow.


The diameter of the bank is ca 300m and is centred in the next field on a depression (the pond) where incidentally there are also some very large standing blue lias slabs of unknown function.

It appeared from the landscape survey and the LIDAR images that we were dealing with a pre-historic enclosure of some sort intriguingly similar to the oppidum discovered in Ilchester. In 2012 a trench was dug across the feature under the guidance of an archeologist but failed to find any evidence of any archaeological significance.

The tile for the northern boundary of the southern part of the parish immedialtely adjacent to the Fosse Way (the diagonal top left) was also purchased. This was to examine if there was any evidence of a stucture at the highest point within this part of the parish. This possibility resulted from a geophysics survey of the area which showed possible evidence. As of this November 2013 this has not been investigated further.
