High Density Survey (HDS) / terrestrial LiDAR data sets are very large and complex. Often they exceed 100s of million’s of points. In the past, distribution of these data was very difficult and required the purchase of expensive and complex specialized software. The goal of the Internet Virtual Metrology Lab (InVirMet) is to facilitate the remote access, measurement, analysis of these 3-dimensional data in a manner that increases the number of people who can use these extraordinarily rich data.

Within InVirMet, visitors may access numerous 3D models created from laser scanning projects conducted by CAST. These models can be downloaded and viewed using IMView, a free 3D data viewing and analysis software provided by InnovMetric, makers of the Polyworks software suite. Using IMView, users can view and manipulate the 3D models as well as extract basic 3D measurements (distance, angle, radius, etc...).

As CAST researchers complete projects, data are made available in the InVirMet Data Repository from long range, landscape-based surveys and from close range, high definition scans of objects.  Currently in InVirMet, there are data available from surveys at Machu Picchu, Peru and Tiwanaku, Bolivia as well as from local surveys of buildings around the University of Arkansas campus.  Also get a glimpse of some high resolution Native American pottery that will become part of an online museum in 2008.  CAST researchers are also working on a number of different data sets from Ostia Antica, Italy; Samaipata, Bolivia; and Amarna, Egypt - so check back for the introduction of these datasets into the InVirMet Data Repository.
