Drone Surveys: Ground Control Points

For an construction or architecture firm to make the most of their drone hardware, especially in the pursuit of accurate orthomosaic or photogrammetry based surveys, Ground Control Points (GCPs) are an absolute must. These strategically placed decals around your survey area provide a reference point for post-flight analysis.

Placing three or more in your survey area will provide a frame of reference for scale, orientation, and elevation. Ground Control Points are affordable and reliable, and a must to include in every surveyor’s toolbox.

Check out some of our most highly recommended GCPs: plain black or multi-color (affiliate links).
