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
Level 1 data products are provided in both .las and .ply formats. Raw sensor output (PLY) is converted to LAS format using the ply2las extractor; ply2lasextractorcode is available on GitHub.
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.
