Databeers Descends on Digital Scholarship!

Last week over 150 data enthusiasts descended on the British Library as the Digital Scholarship Team played host to Databeers – London, a global data-oriented networking group started in Spain and now in over twenty cities around the world. There is frankly nothing more fun for us than downing some beers, listening to great data talks, and introducing the British Library to a whole new audience---particularly those who may not have considered the Library as anything other than a staid place with a whole lot of old books, let alone ventured through the front doors

Home to the UK Web Archive, Turing Institute and a staggering amount of digital collections and data, the British Library is a thriving place for data-centric research and our team is here to support that  innovative use of the Library’s digital content.

To get a sense of the many ways in which we do this, pop along to our upcoming 5th Annual BL Labs Symposium on Monday 30 October 2017, our annual networking and awards event showcasing interesting projects which have used the British Library's digital content over the past year.

Imaginary Cities – Collaborations with Technologists

Posted by Mahendra Mahey (Manager of BL Labs) on behalf of Michael Takeo Magruder (BL Labs Artist/Researcher in Residence).

In developing the Imaginary Cities project, I enlisted two long-standing colleagues to help collaboratively design the creative-technical infrastructures required to realise my artistic vision.

The first area of work sought to address my desire to create an automated system that could take a single map image from the British Library’s 1 Million Images from Scanned Books Flickr Commons collection and from it generate an endless series of everchanging aesthetic iterations. This initiative was undertaken by the software architect and engineer David Steele who developed a server-side program to realise this concept.

David’s server application links to a curated set of British Library maps through their unique Flickr URLs. The high-resolution maps are captured and stored by the server, and through a pre-defined algorithmic process are transformed into ultra-high-resolution images that appear as mandala-esque ‘city plans’. This process of aesthetic transformation is executed once per day, and is affected by two variables. The first is simply the passage of time, while the second is based on external human or network interaction with the original source maps in the digital collection (such as changes to meta data tags, view counts, etc.).

The second challenge involved transforming the algorithmically created 2D assets into real-time 3D environments that could be experienced through leading-edge visualisation systems, including VR headsets. This work was led by the researcher and visualisation expert Drew Baker, and was done using the 3D game development platform Unity. Drew produced a working prototype application that accessed the static image ‘city plans’ generated by David’s server-side infrastructure, and translated them into immersive virtual ‘cityscapes’.

The process begins with the application analysing an image bitmap and converting each pixel into a 3D geometry that is reminiscent of a building. These structures are then textured and aligned in a square grid that matches the original bitmap. Afterwards, the camera viewpoint descends into the newly rezzed city and can be controlled by the user.

At present I am still working with David and Drew to refine and expand these amazing systems that they have created. Moving forward, our next major task will be to successfully use the infrastructures as the foundation for a new body of artwork.

Drew Baker

Drew Baker is an independent researcher based in Melbourne Australia. Over the past 20 years he has worked in visualisation of archaeology and cultural history. His explorations in 3D digital representation of spaces and artefacts as a research tool for both virtual archaeology and broader humanities applications laid the foundations for the London Charter, establishing internationally-recognised principles for the use of computer-based visualisation by researchers, educators and cultural heritage organisations. He is currently working with a remote community of Indigenous Australian elders from the Warlpiri nation in the Northern Territory’s Tanami Desert, digitising their intangible cultural heritage assets for use within the Kurdiji project – an initiative that seeks to improve mental health and resilience in the nation’s young people through the use mobile technologies.
