About this item
- 24”x24” AERIAL TARGETS - Designed for low to medium altitude drone mapping and scanning, these drone GCPs were made for drone mapping up to 400 feet. The standard size is useful when scaling and verifying the map, providing a standard reference distance during post-processing.
- DRONE GCP WITH CENTER PASSTHROUGH - The center passthrough design allows pre-established survey stakes or survey markers to be slid directly through the GCP for added convenience when mapping. Using the passthrough, a surveyor can place markers days or weeks prior to the flight mission. The GCP can then be placed over the existing markers with precision as the surveying marker remains in place during the placement and retrieval of the aerial targets.
- LIGHTWEIGHT & DURABLE AERIAL TARGETS - Using a weatherproof mesh material, these GCPs were made to be highly visible yet lightweight, a big benefit when traveling or placing the GCPs in the field. The material is made with a matte finish which reduces glare from sunlight and overexposure on sunny days, which makes selecting the center of the target easier during post-processing.
- GCP WITH SOFTWARE COMPATIBILITY - These GCPs are compatible with many popular photogrammetry reconstruction software from the leading companies in the space drone mapping, photogrammetry, and surveying space,. The GCPs are compatible with most auto-detection software, and these GCPs have been used in a wide range of industries and educational training programs with great success.
- UAV GCP WITH CORNER ANCHOR POINTS - With eyelets at each corner to easily anchor the aerial targets, the corner anchor points prevent the GCPs from moving during mapping. The anchors also allow the GCPs to be left in the field if needed for repeat flights over a period of time, providing peace of mind that the GCPs offer repeatable location data for high-accuracy mapping and photogrammetry.

- SWG - Columbus, OhioExcellent tool for drone mappingProfessionally, I am a Civil Engineer and I like to use drone technology for mapping. I had a personal mapping project of my property where I wanted to track some progress of trail construction and align it with my property boundary.
I was able to situate these at multiple property corners, fly my drone over the area for mapping and clearly see these targets on the ground; even in wooded areas (flew in the winter with no leaves).
These specific targets do not have the larger center hole for property pin centering, but what I did was put the 'numbered' square corner up to the center of the pin and then staked down my corners to hold the target firmly in place. This allowed me to fly the property and know that the numbered squares are the corners - which is a consistent way to align the map with my boundary survey.
I flew at 185 ft (1.5cm/pixel for DJI Phantom 4) - I have trees I have to clear and 190' of topographic relief on the property). The numbers were very easy to read at this elevation. Since my 185' was fixed, down in the low points of the property, I was over 350' of elevation delta between the drone and target - still readable! I then flew at 235' feet (2cm/pixel) and still readable - at over 400' in elevation to the target. This target was also in a wooded area.
The targets are durably made. I can see them lasting for a lot of uses. I can also see that if a construction company wanted to monitor a job site over a period of time, these can likely withstand staying in the field for a few months - they might fade under UV light based upon the material type; but they are inexpensive to replace. You can possibly stake these down with better stakes - or mount to a hard surface with fasteners and even have an elevation target to use.
Overall - if you are doing drone mapping, these are a better tool than some of the 'homemade' solutions - especially at the price of plywood materials and paint; I would definitely recommend them. They are inexpensive solutions that provide reasonably accurate results. - Tyler BUAS&Manned Aerial Survey TargetsI’ve purchased hundreds of these for our remote sensing projects. Great quality and fast shipping. We prefer the 48x48 because it’s easier to see in the LiDAR data. I wish they would do away with the center eyelet and make it triangular flaps to the center. That’s what I normally have to rip out the second I get them so my nail doesn’t get disturbed picking them back up.
- Techtester1Good targets for RTK requirementsVery sturdy and well thought out.
- Seth FordGreat product!Love these targets! Haven’t frayed, ripped, or become less useful in any way. Used roughly under land dev work and still performs. Good ad hoc takeoff/landing pads, too.
- LMGreat targets, cheap stakes.Much easier to pick out than any of the home made solutions I’ve used. 4 stars because the stakes that come with are useless junk.
- BreEasily SeenBought these for work. They work great and can be seen on LiDar flights we do. Easily seen from 100-400 AGL
- Alexandra OliveiraResistant, very good contrast and clearly visible from the airNothing to dislike so far, particularly in unconsolidated terrain (soil/sand). I have used it as ground control points in photogrammetric UAV flights. The material is light, so it is easy to carry. The center has a hole minimizing damage with topographic poles. Corners have metal seal rings to fix the target to the ground using stakes. I am very pleased with this product.
- A. B.good quality and workmanship.these work nicely out in the field and I expect them to hold up over time
