Introduction and operational framework
CyArk Europe is a registered charity in Scotland, number: SC044310
Our Mission
CyArk is dedicated to the digital preservation of cultural heritage sites through the use of innovative methods,
to collect, archive, and provide open access to data created by laser scanning, digital 3D modelling, and
other state of the art technologies.

The CyArk outline
CyArk’s progressComplete or partial survey data from over 100 sites internationally
The Royal Kasubi Tombs | Uganda
The Scottish Ten project
CyArk, in partnership with Historic Scotland and the Glasgow School of Art’s Digital Design Studio aims to digitally document 5 Scottish UNESCO World Heritage Sites and 5 international cultural heritage sites.
So far, 9 cultural heritage sites have been documented, including 5 Scottish sites:
New Lanark Neolithic Orkney
The Antonine Wall
Edinburgh Old and New Town
St Kilda
?
The Eastern Qing Tombs, China
Rani Ki Vav, India
Mount Rushmore, US
The Sydney Opera House, Australia
Unannounced
Working with partner countries to record 5 international sites (field data for 4 completed):

CyArk’s operation
• Individually funded projects• Philanthropic donations• Working with partners – Skills and knowledge transfer– Dataset donation– In kind support

Project workflow
Handling data
• Appropriate operational best practice– Ensure file-level metadata is maintained, e.g. Exif– Consistency of RAW and lossless formats– No decimation, reduction, sub-sampling or
compression of data • Security and fixity– Storage redundancy and multiple backups– Monitor integrity of data with checksums
Data collectionDigital documentation tools and methodologies
Principal capture techniques include:- Laser scanning survey- HDR digital photography- Photogrammetry
ProcessingData-transformative workflows
Laser scanning data
• Raw scan data import• Registration (and georeferencing)• RGB colourisation• Quality assurance/control
Field capture
Output dataset
Photographic/photogrammetric
• Input image selection• Processing algorithms/software• Parameters (texture, resolution settings)• Quality assurance/control
Producing deliverables
Common project outputs and media include:
• Rendered animations• Textured 3D models• Architectural CAD
drawings (and other survey outputs)
• Interactive game environments
• Panoramic virtual tours

Deposited & donated projects
Archival ingestion
Dissemination
ArchivePractice
• Standardising dataset structure• Conversion from proprietary to open formats• Format specific conversion: e.g. Point clouds –
ASCII XYZRGB/I point data• Generating ingestion metadata
System
• Scalable 2PB LTFS with Crossroads Strongbox• Media and data integrity verification (checksum)• Periodic off-site backup to secure, underground
Iron Mountain facility• Data migration
Dissemination
• Database driven website• Embracing open access– Site multimedia released
under Creative Commons license
– Free access to 3D viewer for point cloud data and 3D models
– Lesson plans (K-12 education)• Developed own tools…
Web
• Project/site information and historical context
• Links to interactive educational content, lesson plans
• Designed to be social-media friendly, e.g. unique content URLs and comment system
SiteManager
• Bespoke web based GIS
• Embedded multimedia content with metadata from datasets
• Management with content type filters, layers, hierarchies and sub-areas
