Survey of Conjunto 16, Room 4, Machu Picchu with the Optech ILRIS-3D

Creator(s): Katie Simon

Year: 2009


Conjunto 16, room 4 is a structure located in the Western Urban Sector of the world-renowned archaeological site Machu Picchu, in Peru. Room 4 sits just to the east of the Sacred Plaza and open terraces.

The Center for Advanced Spatial Technologies (CAST), University of Arkansas conducted high density surveys of Conjunto rooms as part of a UCLA field school in 2009. During the field school, students acquired the 3D survey data while learning about different mapping and documentation standards. CAST researchers completed the additional data processing.

CAST researchers and field school students completed scans of Conjunto 16, room 1 and room 4. See the following tDAR address to view the scan of room 1:

This record presents the 3D data for Conjunto 16, Room 4. It provides the original scan data and the merged point cloud.

Optech ILRIS-3D, Serial No.:10162, meters

Company Name:

Center for Advanced Spatial Technologies

Turntable Used:


RGB Data Capture Information:

NA. Color information was not acquired for the scans however intensity data is automatically acquired with the ILRIS 3D.

Control Data Filename:


Planimetric Map Filename:


Description of Final Datasets for Archive:

Original scans (unedited, prior to registration) in e57 format, transformation matrices for each scan, registered point cloud in ASCII format, polygonal mesh in OBJ format. NOTE: Prior to registration all scans were edited to remove extraneous data. The edited scans were imported into Polyworks IMAlign (and gridded) and then registered. The transformation matrices from the edited scans were exported and are provided here with the original, unedited scans. The polygonal mesh contains supplemental data from the 2005 Machu Picchu Site Survey using the Optech ILRIS-3D.
