For PPK workflows, we recommend 1–3 AeroPoints for sites up to 150 acres (60 hectares). For each additional 50 acres (20 hectares), you need 1–2 additional AeroPoints.
For non-PPK workflows, a set of 10 AeroPoints will deliver accurate results on areas up to 180 acres (80 hectares). Even for the smallest surveys, such as a single building, we still recommend putting out all of your AeroPoints – it’s easy to do, and gives you the ability to verify accuracy and avoid accidental movement or obstruction that could ruin your survey.
We recommend two sets of AeroPoints (20 total) for high accuracy on areas up to 360 acres (145 hectares).
