From time to time something comes along that catches our eye, and if we can help we will.
Dig the Street is a Facebook page run by a group of folks dedicated to making sure the car park at the former Weymouth & Portland Borough Council offices is subject to a full archaeological investigation.
On the face of it the location offers little historical inspiration, with what can only be described as a 1970s eyesore of an office building dominating the scene.
But the former high street runs right under the car park and the historical town walls set the backdrop. During the English Civil War the area bore witness to the Battle of Weymouth as Royalist fought Parliamentarian for control of the town.
The area is slated for development and two trenches were opened to investigate what lies under the tarmac.
Scan with Scale
With limited opportunities to travel it made sense to ask Grahame Knott of Deeper Dorset to nip along with his camera and shoot the images needed, including the all-important scale bars to make sure we add the value of accuracy to the model.
A few hundred images later the results were ready for processing and turning into a scaled 3D model. Error values within the 3D models were within the sub-millimetre range and by analysing the DEM we could let the diggers know the volume of the soil removed from each trench.
The photogrammetry output are below and today sees the excavation wound down. We do hope what was found will justify a complete excavation before the site is developed.
We like to support projects like this. If you have something worthy and can see how photogrammetry might help please use the contact page to get in touch.
