Similar to traditional ground control, the more AeroPoints you use, the better the results you'll get. AeroPoints work collaboratively to correct against each other, so the accuracy of each unit increases when more AeroPoints are laid out.
We recommend using the full set, even for small sites, to increase redundancy and accuracy.
Using the traditional AeroPoint workflow, a full set of 10 AeroPoints can cover a maximum of 180 acres (0.72 square kilometers). In practice, however, we suggest that you assume a more conservative 100–120 acre maximum.
For best results, use this placement pattern:
If the AeroPoints are not distributed evenly across the site, the accuracy of the model will be negatively affected. Think of your site like a tarp on a windy day.
You need stakes (i.e. AeroPoints or other ground control points) to keep the tarp (accuracy) from blowing away. If all the stakes are in one corner, the rest of the tarp will keep getting blown about. If there are no stakes in the center, it won't stay put.
The same goes for AeroPoints. You need a stable ground-level base with even distribution.
Remember, AeroPoints need to be collecting data for at least 45 minutes to get accurate data. These instructional videos capture best practices for laying out your AeroPoints and collecting data.
With the PPK workflow, more acreage can be covered with a set of 10 AeroPoints. See this article about the PPK workflow for more information.
I still can't do it!
