Ground Control Point Planner
Plan smarter control for your mapping jobs. This tool recommends a practical mix of Ground Control Points (GCPs) and independent checkpoints (ICPs) based on site size, terrain, vegetation, GSD/target accuracy, and whether your imagery has RTK/PPK or obliques. It suggests interior spacing, shows a simple placement sketch, and exports a CSV for your field crew. Use it to scope field time and QA—then fine-tune for access, safety, and your survey standards.
Note: Keep ICPs independent, anchor corners + center, and prioritize clean capture (overlap, sharpness) over “more targets.”
Ground Control Point Planner
Project type
Terrain complexity
Vegetation / occlusion
Rule-of-thumb density scales with area & site complexity.
Provide to generate a placement diagram & CSV.
If blank, tool assumes ~3×GSD typical photogrammetry performance.
Optional, but improves the recommendation.
% of total targets
We recommend 20–40% depending on QA rigor.
Heuristics: 5 anchors (corners+center) + density by area & complexity; obliques reduce ~10%; vegetation increases 20–50%; RTK/PPK shifts more to checkpoints.
