Maptek I-Site high
performance laser scanning technology proved its value during the recent
project by the Scottish Ten to record
the Sydney Opera House in 3D.
The I-Site 8810 and
I-Site 8800 ultra-long-range scanners captured the Opera House from all angles,
including critical surroundings such as the plinth that the Opera House sits on
and the main structure itself.
The Scottish Ten is a
project which brings together Historic Scotland, Scotland’s Government heritage
organisation, 3D scanning experts from the Digital Design Studio at Glasgow
School of Art, and California-based digital heritage organisation CyArk. The Scottish Ten team worked closely with the
Sydney Opera House Trust to facilitate the 3D scanning project.
Maptek was approached
because our 3D technology, designed primarily for mining, is able to quickly
cover large geographical areas. Scanning from vantage points such as Fort
Denison, Mrs Macquarie’s Chair, the Sydney Harbour Bridge and Circular Quay
ensured capture of the best possible detail of the Opera House setting.
‘The Maptek team covered a huge amount of
ground in their time on site with us, and the data looks fantastic. Their
enthusiasm and support has been phenomenal and it has been our pleasure and
privilege to work with them’, said Dr Lyn Wilson, Scottish Ten & CDDV
The I-Site laser scanner was
mounted on a vehicle to drive through the Royal Botanical Gardens to scan the
southern and eastern aspects of the Opera House and Sydney Harbour Bridge. The ability to set up so quickly, obtain the scans and move between
strategic locations meant Maptek could
‘fill in the pieces of the puzzle’ that
the Scottish Ten scanning pass did not capture.
The Scottish Ten team has used aerial scanning to
collect data of the setting for other sites.
I-Site terrestrial laser scanners allowed
them to collect the same type of data for the exterior and interior of the Opera
More importantly it meant accurate portrayal of
vertical structures and the complex engineering of the underside of the Harbour Bridge, not
possible with aerial methods.
The long range
scanning ability of the I-Site 8800 and I-Site 8810 was ideal for this project.
Complicated access to built and natural environs, including an island in the
middle of the Harbour, and tight deadlines meant efficiency was the key. In all, 144 scans of different resolutions were captured over 3 days,
with more than 100 different set ups.
Simultaneous capture of high resolution colour
imagery with I-Site systems allows for
spectacular animations and realistic models which reflect the unique beauty of
the Opera House in its setting.
Maptek I-Site Studio
software easily registered the scans in local coordinates. Base scans from key
positions established survey control, streamlining setup and capture of remaining scans. Dynamic
transformation and registration tools, adjusted the new scans to the reference
scans, bringing the data into its correct spatial location.
The Sydney Opera House is one of the world heritage
sites being scanned for the Scottish Ten project. The ultimate goal is to cover
five sites in Scotland and five in other parts of the world. Laser scan data
will be used to create 3D models to preserve the sites for posterity.
Maptek technology has also been
used to capture the landscape and ruins on the remote island of St Kilda, about 100 miles off the west coast of Scotland. This is one of only
28 World Heritage Sites around the globe with dual recognition for natural and

Scottish Ten Project
The Scottish Ten is an ambitious
five-year project using cutting edge technology to create exceptionally
accurate digital models of Scotland’s five UNESCO designated World Heritage
Sites and five international heritage sites in order to better conserve and
