Introduction and operational framework
CyArk Europe is a registered charity in Scotland, number: SC044310

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. Natural and anthropogenic threats
Urban Sprawl
Arson
Pyramids at Giza, Egypt Sungnyemun Gate, Seoul, South Korea
Flooding
Piazza San
Marco, Venice, Italy

5. Complete or partial survey data from over 100
sites internationally
CyArk’s progress

6. The Royal Kasubi Tombs | Uganda

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. 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. Working with partner countries to record 5 international sites (field data for 4
completed):

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

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. Data collection
Digital documentation tools and methodologies
Principal capture techniques include:
- Laser scanning survey
- HDR digital photography
- Photogrammetry

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. 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. SiteManager
• Bespoke web based
GIS
• Embedded
multimedia content
with metadata from
datasets
• Management with
content type filters,
layers, hierarchies
and sub-areas
