Well, following on from my previous post, my Day of Archaeology turned out to be rather different than planned. This is certainly not an unusual occurrence; working in archaeological computing in a commercial environment, all manner of things can crop up and cause the most carefully planned day to head off in another direction altogether.
Firstly, my LiDAR data didn’t arrive so that bit went out of the window. And a whole bunch of meetings were convened, so a big chunk of the day was spent planning upcoming projects and working on management topics. I did end up doing a bit of survey support, preparing some survey instruments for the following weeks work and helping one of the Wessex Archaeology fieldwork teams with a GNSS problem they were having. I also devoted some time to preparing a submission for a metric survey project which will include some Terrestrial Laser Scanning (TLS) and some Polynomial Texture Mapping (PTM), a form of Reflectance Transformance Imaging (RTI). I also looked at the final specifications for another TLS project due to start fieldwork imminently. TLS is rapidly becoming the most efficient and cost effective means of capturing 3D metric data for recording and analysis of archaeological sites, structures and landscapes and one aspect of my job is managing such projects. I also currently do much of the processing, analysis and visualisation work on the resulting point clouds (and watch out for some videos of previous projects coming soon to the Wessex Archaeology Computing Blog).
But by far the best part of the day was spent doing one of my favourite activities: Systems design and development. I am currently building an integrated GIS & database application for managing and interpreting marine geophysics data. As with any good software application, it needs to effectively support the processes applied by the users, in this case the marine geophysics team. The data structure needs to be based around a solid and robust model of the information recorded; it needs to record not only the raw and interpreted data but the necessary Quality Assurance and metadata needed for analysis and reporting. I do enjoy this kind of work as it is creative and logical at the same time and to get it right, one needs to understand the detail and nuances of the processes being developed for, a good opportunity to find out more about different areas of archaeology (I have previously developed context recording systems for archaeological fieldwork, diver recording systems for marine archaeology and a variety of recording and analysis systems to support projects such as Environmental Impact Assessments and Conservation Management Plans).
My evening was indeed spent as planned finishing off a paper for publication. Whilst my main interest is in archaeological spatial technologies, I also have research interests in the application and development of data standards, thesauri and ontologies. My paper was based on how these various strands are coming together to support and arguably change the way in which archaeological theory is formulated, giving archaeologists the tools to discover information more easily and then develop more data driven theoretical assertions.
So a little bit different to what I had planned but I do hope still of interest to some.
