I completed my cheap photography project last month, and added it to my early Swansea coal history book.
The history of Swansea coal is being lost amongst all the noise and gravy train funding for the Hafod/Morfa Copperopolis story. My work on Swansea coal is meant to redress some of that imbalance and cast new light on a part of the Lower Swansea Valley that isn’t considered important.
The photogrammetry was a great success, completed for a few hundred pounds rather than the thousands claimed by local firms. The constraints were to use second-hand cameras and computers, and to provide imagery of a quality and level of detail that would prove useful. No drones were used as we found that they were adding a layer of costs and complexity that was distorting the value of what should be an extremely cheap and quick process.
After discussing the protocols with a couple of BIM colleagues, I looked at the protocols described in this 2011 paper (listed below). Despite being a little older than the average BIM work these days, the workflows were good, easily replicated, and I could learn how to use simpler, older cameras for the imagery.
There was a series of trials of various landscape and heritage features, ranging from riverside bollards, dock walls, and larger landscape features such as bomb craters and threatened landscapes. The larger subjects needed drone input, and so they were discarded, although some beneficial results were obtained for researching biodiversity and small-scale features which I’ll follow up in a later project.
The study subjects were the Foxhole River Staithes, which were of good size (typically about 8m wide, 3m high) and interesting construction. The photographic survey took just over three days, with about four thousand images collected. Office processing of the imagery took about three days.
The photogrammetry was included in a book giving a brief history of coal in Swansea and the significance of the Foxhole area in pre-industrial Swansea.

“The Foxhole River Staithes are a set of enigmatic structures on the banks of the River Tawe near the remains of the White Rick Copper Works. Although now hidden by trees and slowly deteriorating, they were once the centre of the incredible coal industry that dominated Kilvey and Foxhole in Swansea. This book describes the history of coal in early Swansea and explains the significance of the last remaining structures of the coal industry of early Swansea before the arrival of copper smelting in the 1730s. The story of the coal mines of Swansea, the coal export trade and the ships that visited eighteenth-century Swansea are all described. The book also includes the results of photogrammetric surveys of the surviving structures to give the story of the true significance of the Foxhole Staithes and their place in Welsh history.”
