Utilizing 3-dimensional Trimble & Leica laser scanners, CNA is able to create highly precise point clouds. Capturing millions of measurable points in a 3D format, we are able to visualize large areas quickly and record details that are otherwise difficult to convey. This data can then be used in a multitude of ways, such as 3D surface modeling, architectural visualization, as-built recording, building information modeling (BIM), CAD map drafting, construction progress tracking, monitoring fixed features, building quality inspection, and recording accurate measurements.
Point clouds are created by ground-based field measurements using highly accurate 3D scanners and unmanned aerial system (UAS) drones. The drones can also produce point clouds from aerial photography. The aerial photos are compiled into a point cloud by software which triangulates common points in the photo set. This method of point cloud creation is referred to as photogrammetry.
