Digital Past 2018 Aberystwyth 7-8th February

Digital Past 2018 Aberystwyth 7-8th February

I’ve had a busy few months since the start of this year so a bit guilty of not posting as frequently as i should…

I’ve been cracking on with my progression to PhD report so spending a lot of time writing at my desk and also doing some test SFM photogrammetry of older photographs with help in Bradford Visualisation.

For the last few months I’ve been planning and arranging a roundtable discussion with Chris Casswell, Head of Fieldwork at DigVentures, on the theme of 3D data management and archiving. Me and Chris both work in acquiring and analysing 3D digital data in the field – particularly for SFM photogrammetry and terrestrial laser scanning. We thought it would be useful to host a session on the topic of data management and archiving as we deal with lots and lots of data, which takes up a great deal of space, and thought it would be good to bring together individuals from a range of different institutions and companies within the heritage sector, to hear what they do and as an opportunity to raise issues in how 3D data is dealt with at an archiving stage.

As Digital Past brings together many people with an interest in digital heritage, we thought it would be the ideal venue for the discussion, and we set up a workshop to bring together professionals in the field and get the ball rolling on how we can think of dealing with these matters. More news on that to come in future!

Overall it was a really good two days in Aberystwyth. The conference was great for catching up on how some major digital projects are progressing in the UK and hearing about new innovative work that’s being done, as well as meeting up with colleagues from all over the country!

I thought Aberystwyth is a quirky and scenic seaside/student town with very pretty architecture and lots of nice bars and restaurants – I wish I had more time to explore and will definitely have to return to this part of Wales, which I’ve never been to before!

Many thanks to the organisers of Digital Past for hosting our session, I’m looking forward to next year’s conference!


Winter update – much desk-based research and TAG Cardiff 2017

Winter update – much desk-based research and TAG Cardiff 2017

Happy New Year everyone! I’ve been tucked away at my office desk for the last few months doing much reading so I’m a bit guilty of not posting for a while…

For a while now I’ve been busy processing some of the laser scan data from last summer’s fieldwork, and also working on some of my PhD writing. This is fascinating stuff for me as I delve into past research into brochs and 3D imaging, but I haven’t got so much to blog about in the meantime!

However, I did travel down to Wales for the annual TAG conference, just before Christmas. I’ve never been to Cardiff before so it was exciting to experience a new city. I was invited to give a paper in the session “How to See Time: A Visual Culture Perspective”, that was organised and chaired by Felicity McDowall, Lisa-Elen Meyering and Katie Haworth from the Leverhulme Centre for Visual Arts and Culture at Durham University. It was a great experience and all of the talks generated some very interesting discussion, with gave me much food for thought for my PhD, particularly about how to visualise different time periods in a single space, and how digital data might be used to show the passage of time at an archaeological site.

I didn’t come last in the TAG quiz and really enjoyed the carols performance by a traditional Welsh choir during the TAG party. Hopefully I’ll be able to see a bit more of the city next time I visit!

I’m back in Bradford now and busying away at reports and further desk-based research, but I’m also preparing for the workshop that me and Chris Casswell of DigVentures are hosting at next month’s Digital Past conference in Aberystwyth. We’re running a roundtable discussion on managing and archiving of 3D datasets (from photogrammetry and laser scanning) and ideas for best practice in the archaeological sector. Speakers from national heritage bodies, commercial archaeological units, universities and the Archaeological Data Service will be participating, so we’re hoping for some really interesting and useful discussion for all involved!

Travels to Thurso, Caithness and Brochtoberfest!

Travels to Thurso, Caithness and Brochtoberfest!

This blog post comes a fair bit delayed as I’ve been so busy travelling to different events over the last month (and now settling back into scan processing in the office at Bradford), but I wanted to say thanks to Iain McClean and Ken McElroy of the Caithness Broch Project for inviting me up to Thurso to speak at their fantastically-named Brochtoberfest seminar – an annual event where broch-related researchers and enthusiasts gather to hear about the latest in broch-related studies and archaeological work. It was a sell-out event, and located in the wonderful Caithness Horizons Museum – well worth a visit to see its impressive collection of carved Pictish stones.

It was great to meet other broch researchers and be informed on the many interesting activities being done to study and present these sites and their archaeology. I also got to see the impressive Lego broch model on display in the museum, which was fun (much heated discussion was heard about the features the model includes, and also the technical difficulties of modelling a round tower using square bricks…!). Dr Samantha Dennis also brought some artefacts from the Old Scatness Broch excavations with her, for her presentation on cataloguing the finds in the Shetland Museum, which were great for the attendees to handle.


The famed Lego Broch on display at Caithness Horizons! The level of detail is fanastic – note the smoked fish inside, and intra-mural galleries between the walls!


I must add a thank you to the owners of Pennyland House B&B for their kind hospitality during my stay in Thurso. I explored the town and nearby Scrabster the day after the festival, before I caught the train back down south (main image at the top shows the view of the island of Hoy, Orkney, from outside Pennyland House, plus some rather sleepy sheep!). An interesting fact: Thurso station is the most northerly in the UK, so I travelled quite literally to the end of the line! It’s a very scenic journey, spotting many deer and birds of prey on the way. I must visit some of Caithness’s broch sites the next time I am in northern Scotland.

The return to Orkney: Our Islands, Our Past conference 14th-17th September

The return to Orkney: Our Islands, Our Past conference 14th-17th September

Last week I returned to Orkney (less than two months since I was there last!) – setting off at the crack of dawn in the northeast of England and making the epic drive to the most northerly point of mainland Scotland, before catching the shortest ferry crossing to take me over to the Northern Isles – again! I did drive over the new Queensferry Crossing, which is very impressive (I’ve now crossed all three Forth bridges in a year!). I also stopped off at Inverness to see the cathedral, have a bite to eat and a stroll along the river which was lovely. The purpose behind this exciting road trip (8 and a half hours on the road not including breaks!) was to give a paper on outlining the ideas and aims of my PhD at the Our Islands, Our Past conference, held by the Archaeological Institute at the University of the Highlands and Islands (UHI) in Kirkwall. I also wanted to see a few sites I hadn’t done on my first visit to Orkney and ambitiously hoped to see the Northern Lights if the weather conditions were right…

Driving over the Queensferry Crossing on its first full week of running

I caught the morning ferry from Gills Bay, near John ‘O Groats, to St Margaret’s Hope on South Ronaldsay. It was my first time on this island, so I visited the famous Tomb of the Eagles, a Neolithic chambered cairn 5000 years old. (I chose to “skateboard” into the cairn as it was quite muddy, and appreciated borrowing some waterproof trousers the visitor centre thoughtfully has prepared for visitors!). The coastline walk around the site has some dramatic cliffs, and I spotted a seal sunning itself in the bay, as it was incredibly bright outside (but windy!).

It’s a bit of a squeeze through the Tomb of the Eagles passageway!

Last time I was in Mainland Orkney I was a bit pressed for time as I caught a bus to see the sights, and the nice driver let us have a whistle-stop tour of the Standing Stones of Stenness before continuing back to Kirkwall. I knew the site of Barnhouse Neolithic Village was close but I didn’t want to risk missing the only bus back into town for several hours! This time, taking a car (definitely the most flexible and convenient way to travel around Orkney), I walked to the Barnhouse Neolithic village from the standing stones. It is remarkably close (literally the next field along) and I was surprised at how few visitors were there. Perhaps they too had buses to catch! I explored Stromness Museum and the town in the afternoon, which reminds me somewhat of Lerwick in Shetland with its old harbourside storehouses and narrow lanes. On the way back to Kirkwall I stopped off at Unstan Chambered Cairn, and befriended a Shire horse in the next field over…!

Not shy for the camera, this fellow came over to say hello at Unstan Cairn

The day before the conference started I managed to squeeze in some non-prehistoric sites on the mainland, including the Norse settlement on the Brough of Birsay, the Earl’s Palace at Birsay and the Earl and Bishop’s Palace in Kirkwall – which is deceptively Tardis-like! I was amazed by how much of the Earl’s Palace remains and exploring the upper levels you do get a sense of how grand and complex the building was.

My last touristy thing to do was have a guided tour of Highland Park Whisky Distillery in Kirkwall. I’d never been to one before and don’t really know much about whisky making, so it was a fascinating experience (and now I know what the difference between single-malt and blended whisky is!). Nice to have a wee dram at the end of the day too!

Onto the actual purpose of my visit(!) – I really enjoyed listening to the papers given at the student conference held at the St Magnus Centre on Friday by undergraduates and postgraduates at UHI. It was a great idea to combine the student event with the overall conference, encouraging students to present for the first time and giving them good practice for the future, and for visitors to hear about the research they are doing. I wish I had more practice in presenting as an undergrad – it’s a skill little taught at school but essential in academic research. I guess dressing up as a Roman and giving guided museum tours helped me out a bit, but it’s always different being up on stage (quite literally for this conference as it was held in the impressive Orkney Theatre)!

I had a very good time at the main conference. There’s such a wide range of different projects going on in the Northern Isles and it’s always nice to meet new people! Plus the stalls and extra presentations during the breaks were very interesting to see. I hope people liked my presentation. I’ve just started to process and look at the data we scanned from Mousa, so in a couple of months’ time it’ll look fantastic visually, but the audience were the first to see some of the scans registered together, so digital Mousa is being pieced together bit by bit! Many thanks to the organisers for inviting me to speak, and for such a great experience (the Orkney fudge in the conference bag was a nice treat!).

I had to catch the Pentland Ferry before the last session ended sadly, but I did manage to stop off at Doune Castle on the way down to Bradford. It’s where much of Monty Python and the Holy Grail was filmed, and has an excellent audio tour narrated by Terry Jones. As a big Python fan, it was a fun place to see (though I do wish you could climb the battlements to re-enact John Cleese’s taunts to King Arthur as the angry Frenchman…!). Doune itself is a lovely town and the local cafe does an amazing burger!

Back in Bradford now, I’ve got plenty of data to be putting together over the next few weeks. It’ll be exciting seeing virtual Mousa come together!

Laser scan processing at The Engine Shed, Stirling

Laser scan processing at The Engine Shed, Stirling

Last week I’ve been in Stirling to work on my Shetland laser scans at Historic Environment Scotland’s shiny, new Conservation Centre: The Engine Shed! I had a play with the interactive virtual and augmented reality displays that give you a background on the specialist work that goes on here, digital documentation being one of them. The huge map of Scotland comes alive with AR – you can borrow an iPad and see models of historic sites placed in the landscape and find out more about them. Maybe my work can add to the Shetland sites!

I’ve been registering the laser scan data from Mousa for a week, which has given me a good amount of time to practice doing this with the data from the Z+F 5016 scanner (with kind help from HES colleagues!). I’m looking forward to putting all of it together and seeing the broch in a completely new way – already seeing the way the cells’ beehive-shaped ceilings and how the spiral staircase winds up the sides looks brilliant, but this data needs a bit more tidying up before I can show it! When I’m back from Orkney next week this’ll be my next step.

Exploring Lerwick and the Shetland Museum and Archive

Exploring Lerwick and the Shetland Museum and Archive

I had a calm and very pleasant weekend in Lerwick, exploring the town. Got a bit soggy at times but still very scenic, especially the old harbour, but I picked up a knitted souvenir (I’m the proud new owner of a Shetland fisherman’s cap – now my project hat!). I had time to process some initial data and back up and organise so much of it – many many scans and images to keep me busy this autumn and I need to keep track of it all in an organised system!

On Monday I travelled to the Shetland Museum and Archive to have a meeting and a quick stop at the Shetland Amenity Trust’s impressive headquarters. I walked around the museum’s excellent exhibits for quite some time. It’s really well worth a visit and has a great restaurant upstairs – their seafood chowder is sublime. Also I always get excited when I see any merchandise depicting anything Iron Age (unfortunately the period really doesn’t seem to be promoted as well as the Roman or Norse times), so I had a shopping spree buying Mousa and Old Scatness memorabilia to add to my collection! (Thanks Andy for the bottle of Old Scatness ale, by Valhalla Brewery!)

Late afternoon I had a chance to get a quick wander around Clickimin broch, which was just wondrous, exploring the interior with no other visitors about. Even though it is close to the main road, being surrounded by water and a protective wall, it really feels isolated and eerie.

The ferry crossing to Kirkwall in the evening got a bit choppy but I slept through much of it, fortunately! It was an interesting procedure to reverse onto the ferry, and one that me and Andy went through again on Tuesday morning, to catch the ferry from Tingwall over to the island of Rousay. A brief stop at the delightful Betty’s Reading Room and we were off to Swandro!

First visits to Old Scatness Broch and Jarlshof

First visits to Old Scatness Broch and Jarlshof

On Thursday I visited Old Scatness and Jarlshof for the first time. Compared to Mousa, the scale of these archaeological sites are staggering: many roundhouses of different periods surround the central broch at both. As my supervisor Dr Val Turner showed me and colleagues around Old Scatness, James was busy getting laser scans around the site (once you start, you can’t stop scanning)!

Val interviewed me, Lyn and Andy for Radio Scotland about my PhD project and the vision for all three of these amazing Iron Age sites. Her recording was broadcast later that day and on Friday – first claim to fame! I’ll post here and on Twitter when I find out the exact time her more in-depth interview is broadcast.

After data swapping and backing up during lunch at the Sumburgh Hotel, we headed to Jarlshof. The HES team even had time to take a few initial laser scans around the site, following the permanent survey markers that Mike recently installed so the condition of the site can be monitored with accuracy in the future. The long history of Jarlshof is amazing (much more detailed info here:, but the fact that just half of the broch has survived to present highlights just how under threat many archaeological sites are from coastal erosion. The defences put in place at Jarlshof are strong, but it will be useful to monitor them over time and laser scanning can do this with great detail.

After our Historic Environment Scotland colleagues departed on Thursday, me and Andy returned to Old Scatness on Friday to acquire some more scans and take photography for SFM photogrammetry. I laser scanned areas of Old Scatness with the FARO Focus X330 that the long range Leica P40 may not have covered, and by the end of the day much of the site has been scanned and recorded. With permission from Sumburgh Air Traffic Control and DJI, Andy piloted the DJI Mavic SUA over Old Scatness to take aerial photos across the site, giving us excellent coverage which will help to feed into the terrestrial scan data and photos for photogrammetry.

Overall the amount of data acquired on this fieldtrip has exceeded all my expectations! It’s going to look amazing once it’s all been processed (my next major step in the PhD). Tomorrow I’ll be visiting Shetland’s Archives and Museum, run by my external partner Shetland Amenity Trust ( to investigate historic records of my three sites. I’m hoping to get a better sense of their history from past researchers and their notes and images.
