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. All scans were aqcuired for the Capitoline temple from a lift boom which provided the necessary vantage points to aqcuire data for most of the strcture's tall walls. However, as a result of the windy conditions during the survey and the subsequent movement of the scanner/lift boom, there is movement evidenced in most of the scans. The easiest way to spot this movement is to look for a ripple or wave pattern that extends how horizontally across the datset (a result of the scanner/left boom moving up-and-down). This pattern is not always consistent and can appear to varying degrees within and between sans. 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 final registered point cloud has also been provided as a single ASCII file.
