Wrecked in Second Life

A while back I nearly didn’t answer the phone. It was one of those international numbers and I didn’t recognise it but something told me to pick it up.

Accuracy Defined?

Underwater GPS meets Photogrammetry For a while we have been using GPS located cameras to construct highly accurate models of defensive structures known as pillboxes. Fixing a camera position above the waves is straightforward enough and you can build representative models without additional scale bars or measurements if the GPS signal is accurate. The problems Read more about Accuracy Defined?[…]

Deadlines and Detail Having masses of data is a double edged sword. Too little and your images won’t align or your models lack definition. Too much and processing time jumps exponentially. Its always a balancing act between a desire for detailed models and the time available. When The Thistlegorm Project team decided to launch the website on Read more about Can We Take a Closer Look?[…]

Bolt in the Bay – P47-D Crash Site

Background A few years back Grahame Knott of Deeper Dorset found the dispersed remains of an aircraft in Weymouth Bay.

Project Thistlegorm – The Processing Begins
