Heritage Restoration Division

At Sapio, Our Vision Is To Enable Policy Formulators And Stakeholders To Use Intelligence Of Data Thereby, Following The  Mantras Of

  • Conservation & Documentation
Digital Restoration & Conservation of Temples
Sapio is in close engagements with Piql AS (Norway) and Factum Foundation (Spain) to launch a pilot project to investigate and explore the different methods of digitization and data acquisition of the low and high relief walls and statues in Angkor Wat.

Further the ambition will be to establish an archive for the preservation of the digital data obtained during the digitization and data acquisition at Angkor Wat.


Piql is a specialist in the area of long-term digital preservation and archiving of irreplaceable world memory and cultural heritage.

Piql’s unique storage technology will carry information authentically into the future and secure that important information and cultural heritage can be reproduced in its original form.

Piql has established the Arctic World Archive, a secure vault in the permafrost in the arctic island of Svalbard where important world memory is stored and protected for the benefit of future generations.

Factum Foundation

The Factum Foundation for Digital Technology in Conservation is a not-for-profit organisation, founded in 2009 in Madrid. The Foundation was established to demonstrate the importance of documenting, monitoring, studying, recreating and disseminating the world’s cultural heritage through the rigorous development of high-resolution recording and re- materialisation techniques.

The findings from this investigation are aimed to kickstart a major training and preservation initiative to record and store the data acquired at Angkor Wat. The data will belong to the custodians of Angkor Wat for all current and future applications. Factum Foundation has worked over the past twenty years setting up similar initiatives in various sites around the world including the ongoing recording of the Tomb of Seti I in the Valley of the Kings. Sapio has recently tied up with IIT Bombay on the said conservation project.

In 3 weeks (approximately 120 hours)
of on-site-recording, it is estimated
that the following amount of data
will be obtained to be archived.

1 x Lucida 3D Scanner

FOR WALL RELIEFS 120 scanning hours = max.100 scanning tiles = approx. 25 sqm of wall relief 65GB (inc. raw video) x 100 tiles = 6.5 TB of originals files File

Formats: .avi (90%), .ris + .tif + .xml (10%)

1 x photogrammetry kit

FOR WALL RELIEFS AND SCULPTURES 120 scanning hours = approx. 250 sqm of wall relief 10GB (about 125 photos) each sqm x 250 sqm = 2.5TB of originals files File

Formats: .cr2 (80%), .jpeg (20%)

1 x white light 3D scanner

FOR WALL RELIEFS AND SCULPTURES 120 scanning hours 16GB (raw + export data) each hour x 120 hours = 2TB or originals + export files File

Formats: (raw format) (60%), .obj + .stl (40%)


As a representative example of the kind of equipment to be used is as follows.
