This weekend is Freedom Festival. Last year we were having an amazing time running the largest ever Earth Arcade in a big tent in the centre of Hull, talking to hundreds, if not thousands, of people about the environment and the research of the Energy and Environment Institute. It seems such a long time ago now and it seems even longer before we’ll be able to run our Earth Arcade again.
We love Freedom Festival and have run our virtual reality activities during the Festival in 2015, 2016, 2017, and 2019. Honestly, it doesn’t feel right when we don’t get to play. This year’s Freedom Festival is fully online and even though we don’t have an Earth Arcade or are able to place headsets on people, we still have been involved in some of the activities for the Festival.
On Saturday 9th September, watch out for a cameo by Chris Skinner as a “real scientist”, as part of The Reset Lab’s Crazy Ideas programme, 3-5pm BST.
However, our main involvement has been behind the scenes of By Rising Tide of Humber. This brand new 360 video experience has been created by the University of Hull (led by Stewart Mottram) and BetaJester Ltd, funded by XR Stories. In the experience you meet poet Andrew Marvell in streets of 17th Century Hull, witnessing the flooding that he described within his works. The video can be viewed below and you can read more about the project here.
Unusually for us, we were not involved in the creation of the 360 experience itself, instead we used our expertise in using computer models to simulate flooding to recreate the descriptions within Andrew Marvell’s poetry. The flooding you see in the experience has been created using the outputs of our model.
To be able to do this, we needed to recreate 17th Century Hull to use in our model. The most difficult part was actually creating the land the city sits on, with our data coming from the present day and many changes having occurred in nearly 400 years, including building forward into the Estuary. Another issue was that although the data we used had been processed to show land surfaces only, the footprints of buildings and roads were still present and we needed to filter these out. Using this data along with historic maps of the city, we created contour lines for the 17th Century and produced our land surface from this.
The next step was to create the city itself. We added building, walls, roads, drains, and moats using a historical map that had been ‘georeferenced’ by research assistant, Helen Manning. She used identifiable features, such as road junctions and buildings that still exist, to stretch the image over a modern map. Working with Briony McDonagh, we used the map and historical records to add the heights and depths of these features to the land surface we had created.
Finally, we needed a flood. For this we used data for the 2013 storm surge taken from our Humber model. As sea levels were a little lower in the 17th Century we adjusted the water levels down slightly to account for this. We combined all the data together to produce the model in the video below. We then passed all this on to Betajester Ltd and they did their usual VR magic!
