Its has taken some time (a bit longer then planned) but i’m pleased to say that the entirety of Ravens Well has been surveyed and photographed resulting in a complete and accurate (to the disto data) model. The same techniques and equipment that were previously mentioned have been used, some sections proved tricky for the software to understand so I have introduced the coded Metashape markers to provide visual and spatial reference, this seems to have solved the issues in certain sections of passages where the alignment was struggling.
There are some ferrous areas inside as the disto data shows some larger than expected loop closures in certain areas despite careful practice. Metal girders are visible in the far downstream area which is the bit which shows the greatest variation when overlaying my data with the previous survey performed by Axbridge Caving Group.
I’m working on a video walk through of the whole site like the previous version so I will upload this when its complete, here is a quick video overview for now, below is low resolution model uploaded to Sketchfab which you can explore with your mouse/ phone.
