CyArc Europe - Introduction and operational framework

  1. 1. DEDICATE Seminar 21 October 2013 Adam Frost Introduction and operational framework CyArk Europe is a registered charity in Scotland, number: SC044310
  2. 2. 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.
  3. 3. Natural and anthropogenic threats Urban Sprawl Arson Pyramids at Giza, Egypt Sungnyemun Gate, Seoul, South Korea Flooding Piazza San Marco, Venice, Italy
  4. 4. The CyArk outline
  5. 5. Complete or partial survey data from over 100 sites internationally CyArk’s progress
  6. 6. The Royal Kasubi Tombs | Uganda
  7. 7. 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.
  8. 8. 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
  9. 9. Working with partner countries to record 5 international sites (field data for 4 completed): ? ? The Eastern Qing Tombs, China Rani Ki Vav, India Mount The Sydney Rushmore, US Opera House, Australia Unannounced
  10. 10. CyArk’s operation • Individually funded projects • Philanthropic donations • Working with partners – Skills and knowledge transfer – Dataset donation – In kind support
  11. 11. Digital documentation overview Project workflow Data collection Receipt of external data Processing Consumption (deliverables) Dissemination and presentation Archival ingestion and storage Data/metadata management
  12. 12. 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
  13. 13. Data collection Digital documentation tools and methodologies Principal capture techniques include: - Laser scanning survey - HDR digital photography - Photogrammetry
  14. 14. Processing Data-transformative workflows Field capture Laser scanning data Photographic/photogrammetric • • • • • • • • Raw scan data import Registration (and georeferencing) RGB colourisation Quality assurance/control Output dataset Input image selection Processing algorithms/software Parameters (texture, resolution settings) Quality assurance/control
  15. 15. 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 St Peter ad Vincula, Tower of London
  16. 16. Digital curation Internal projects Deposited & donated projects Dissemination Archival ingestion
  17. 17. Archive Practice • • • • 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
  18. 18. 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…
  19. 19. Web • Project/site information and historical context • Links to interactive educational content, lesson plans • Designed to be socialmedia friendly, e.g. unique content URLs and comment system
  20. 20. SiteManager • Bespoke web based GIS • Embedded multimedia content with metadata from datasets • Management with content type filters, layers, hierarchies and sub-areas
  21. 21. 3D viewing tools Church of St. Trophime, France 3D model & point cloud viewer • Measurable • Perspective / orthographic • RGB/Intensity • Clipping box 1.9m pts 338k pts
  22. 22. Interactive/mobile applications
  23. 23. Furthering the mission
