Topographic Survey for Land Development via Unmanned Aerial Vehicle

WSP’s use of an unmanned aerial vehicle (UAV) ensured an accurate, quick, and safe survey while minimizing disruption to the area.

 

WSP’s involvement included:

  • Performing a UAV survey to create a digital terrain model and an aerial imagery map for a one square kilometer parcel of land.
  • Data delivery consisting of a dense blanket of 3D points spaced five to seven centimeters apart, with high-definition colour imagery showing exactly and accurately what was on the ground at that point in time.
  • Post-processing that classified and removed all irrelevant features to compile a true, ground-level digital model.
  • Survey completion in a matter of hours, including control setup, flight, and field QA / QC of the raw data.

Typical deliverables for an UAV operation include true colour orthophotos mosaics, 3D models, and digital surface models at the five to seven centimeter / pixel resolution. Accuracy is typically at the four to five centimeter level. GIS and CAD ready files are available.
