What are Ground Control Points (GCPs)?
Ground Control Points (GCPs) significantly reduce errors in drone GPS data, ensuring precise georeferencing of aerial images with high-precision instruments like RTK GPS, achieving centimeter-level accuracy. These points are marked by highly visible targets and distributed strategically to serve as a reference framework, facilitating the integration of drone data with geospatial datasets & GIS systems. Incorporating GCP coordinates into photogrammetry software is crucial for correcting positional errors in drone imagery. Essential for generating accurate 3D models, GCPs support detailed mapping in agriculture, construction, urban planning, and archaeological studies, as well as assisting scientists and conservationists in environmental monitoring.
TESTIMONIALS
Very efficient and easy to use for any job requiring GCP's. Does come with eyelets for stakes, however the material is heavy enough that I do not find myself needing to stake them down.

These targets are a much, much better material than the traditional vinyl ones. They are a mesh material and therefore allow for some wind to blow right through them making them easier to deploy and stay in position. They are also breathable unlike the vinyl. This is nice for when condensation forms underneath the target and you have to put them away wet. They feel very durable and hefty with a very low chance of ripping and should last much longer. The metal grommet in the center is a nice touch for placing the survey rod. 10/10 would buy again.

After using these ground control points for a couple of jobs, they have earned a place in my work truck. These are easy to put down and work very well. They are quite visible on the drone imagery, and show well in Pix4D when marking!
