Point Cloud Data
3D point cloud data is collected using the Fraunhofer 3D laser scanner. Custom software installed at Maricopa converts .png output to the .ply point clouds. The .ply point clouds are converted to georeferenced .las files using the 3D point cloud extractor
For each scan, there are two .ply files representing two lasers, one on the left and the other on the right. These are combined in the .las files.
Data is available via Clowder, Globus, and Workbench.
- Globus or Workbench File System:
- LAS
/raw_data/laser3D_las
- PLY
/raw_data/laser3D
- The position of the lasers is affected by temperature. We added a correction for temperature to adjust for this effect. See terraref/reference-data#161
