Why AeroPoints Should Be Collected in Reverse Order

The method you take to lay out and collect your AeroPoints can directly affect our ability to process the data they collect. When we correct the AeroPoint positions, they must have overlapping time stamps. 

By picking up the AeroPoint you laid down first last, that AeroPoint’s time-stamps will overlap those of all of the other AeroPoints. This will allow for a more accurate survey of your site and better quality data. 

When you look at the timeline of your AeroPoint survey, you want it to look like a pyramid:


You don’t want the timeline to look erratic like this:

Not only are the capture times greatly varied (and too short), there is no single AeroPoint that was recording for the entirety of the survey. If you do not do this, it will be more difficult to process your data accurately and provide high-quality data.

If you used AeroPoint best practices to capture data, your timeline should look similar to the image below. Point 1 was collecting data for the entire duration of the survey (it was placed first and picked up last).

Plan your AeroPoint layout so that you pick up the first point last, and the last point first. If you are laying them out across a large site, it may be easier to fly your survey from where you dropped the last AeroPoint. Then, you can collect the AeroPoints in reverse order more easily. 

If you are using a mixed fleet of AeroPoint 1s and AeroPoint 2s, collecting them in the reverse order you placed them is still required to capture the most accurate data.

After you fly your survey and collect your AeroPoints, wipe down the solar panels. You can upload the AeroPoints' data to Propeller on-site or later when you have a strong WiFi network.
