APPENDIX I: AEROPOINTS
CORRECTION METHODS
For accurate positions, corrections must be applied to AeroPoints data using
one of the methods below. (Note: some methods have specific logging and/or
placement requirements that should be adhered to.)
a The Propeller
Corrections Network
If you're flying within the Propeller Corrections Network,
then take advantage of our fully automated AeroPoints
correction. This is the simplest way to use AeroPoints.
In countries like Australia, where a national survey system
is in use on most worksites, this data will be accurate
and aligned with other site data and information.
In countries like the USA, the Propeller Corrections
Network is ideal for accurate general mapping, but most
worksites use a local calibrated system, and should
therefore use the known mark correction method
if possible.
Go to propelleraero.com/aeropoints-coverage-map
to see if your site is covered by the Propeller Corrections
Network.
No? Let us know—we're continually expanding our
network coverage.
Global accuracy:
20mm/20mm/50mm (the best available)
Consistency:
20mm/20mm/50mm (the best available)
Internal accuracy:
10mm or less (precise internal reconstruction)
b Using A Known Mark
You can place one AeroPoint at a known survey mark
or benchmark location.
If you have access to GPS rover equipment, you can
use it to create a new known mark. This is the best
approach for worksites using their own site calibration.
Be sure to place an AeroPoint on the known mark first,
and pick it up last—it must be recording data for the
duration of your flight.
We can use data from this AeroPoint, combined with
the coordinates of the known mark, as the reference
point for the other AeroPoints used in the survey.
Global accuracy:
20mm/20mm/50mm
(the best available—dependant on accurate placement
of AeroPoint and accuracy of known mark itself)
Consistency:
20mm/20mm/50mm
(the best available—dependant on using the same
known mark each time)
Internal accuracy:
10mm or less (precise internal reconstruction)
