Aerial surveying is a cost effective and timely solution to calculate volumes for landfills, stockpiles, gravel pits, strip mines, and reservoirs with minimal disturbance of operations at the project site. Aerial photogrammetry technology has a faster turnaround time, higher accuracy, lower costs, and does not interrupt operations. The deliverables also incorporate high resolution, color orthophotography in digital or printed format.
GPI utilizes the latest in LiDAR sensor technology with the full wave form Riegl LMS Q680i LiDAR sensor. The advantage that LiDAR provides for volume calculation over traditional photogrammetric methods is two-fold:
- Accuracy LiDAR allows for increased accuracy over traditional methods in the horizontal and vertical at similar flight heights and with a blanket of point coverage can create more detailed and accurate surface models incorporating areas that may have been missed by manual photogrammetric methods.
- Fast turn-around time, since there is no film to process, scan and rectify; it eliminates several weeks of time. It also reduces time in data processing, once you establish the base grade elevation, very little editing is required to calculate volumes, as compared to manually delineating topography.
