GeoGear (24"x24") Drone Ground Control Point GCP Target — UAV Aerial Survey Marker — Checkerboard Black/White — 5 Reinforced Grommets — UV Resistant Vinyl Mesh — Pix4D DroneDeploy Agisoft Compatible

Why Professional GCP Targets? Ground control points are essential for accurate drone photogrammetry. Without them, your point cloud and orthomosaic can be off by feet in any direction. GeoGear GCP targets are purpose-built for aerial surveying — they provide the high-contrast checkerboard pattern, precise center point, and secure staking system that professional drone mapping demands. Built for the Field We designed these targets because we couldn't find GCPs that worked well enough. Spray paint fades in a day. Printed coroplast warps and glares. Fabric without grommets blows away. Our vinyl mesh targets solve all of these problems: they're durable, matte-finish, UV-resistant, and have 5 reinforced grommets for secure deployment on any surface. The Center Eyelet Difference The center grommet is the key feature. It lets you set a survey rod or stake directly through the center of the target — the exact point your GPS measures and the exact point the software detects. This alignment between your measured coordinate and the auto-detected center is what produces centimeter-level accuracy in your final deliverable. What's in the Box 6-Pack: Six 24"x24" checkerboard GCP targets, each with 5 reinforced grommets (4 corners + 1 center). Targets ship flat and ready to deploy. Single: One 24"x24" checkerboard GCP target with 5 reinforced grommets. Stakes not included — use standard landscape staples, survey nails, or rebar pins depending on your surface.

• Bullet 1 — Size & visibility: 24"x24" AERIAL SURVEY TARGETS — Designed for drone mapping and photogrammetry at altitudes up to 400 feet AGL. Tested with a DJI Phantom 4 Pro (20MP camera) and confirmed visible with clear checkerboard pattern recognition at 100, 200, and 400 feet. The standard 24-inch size provides a known reference distance for accurate scaling during post-processing.
• Bullet 2 — Center grommet: 5-POINT GROMMET SYSTEM WITH CENTER EYELET — Four reinforced corner grommets for staking the target flat to the ground, plus a center eyelet designed for survey rod placement. Position your measurement point at the exact center of the checkerboard pattern — the same point your photogrammetry software identifies during auto-detection. No guessing, no offset.
• Bullet 3 — Material & durability: UV-RESISTANT VINYL MESH — Heavy-duty, weatherproof material with a matte finish that reduces sun glare and overexposure in bright conditions. Withstands rain, mud, gravel, and repeated deployment on rough terrain. Flexible enough to lay flat on uneven ground. Reusable across hundreds of survey projects.
• Bullet 4 — Software compatibility: COMPATIBLE WITH ALL MAJOR PHOTOGRAMMETRY SOFTWARE — The high-contrast black and white checkerboard pattern is optimized for auto-detection in Pix4D, Pix4Dmapper, DroneDeploy, Agisoft Metashape, DJI Terra, and other photogrammetry and drone mapping platforms. Works with any drone equipped with an RGB camera.
• Bullet 5 — Use cases: PROFESSIONAL GROUND CONTROL FOR DRONE SURVEYS — Used by surveying firms, civil engineering companies, construction contractors, drone service providers, and government agencies for topographic surveys, volumetric measurements, progress monitoring, and aerial mapping. Suitable for grass, dirt, gravel, and hard surfaces (use tape or weights on pavement).
