Why clean yield data?

Yield data ALWAYS contain problems
 Operational
problems
 Data
collection errors
 Calibration issues
 Sensor
system related problems
 Sensor
failure, noise, accuracy issues
 Timing/filtering issues for individual sensors
 Multiple sensors can magnify problems

Basic yield calculation
MC  Flow
Yield  k 
Width Velocity

where k is used to account for unit
conversion factors, and MC is a moisture
correction factor based upon a crop
specific market reference.

Dealing with yield map errors





All yield maps contain some errors that should be
removed before analysis
Manufacturers’ software does a good job of
dealing with many simpler problems
They have a tougher time with “trial-and-error”
type settings (i.e. delay time – set, view, adjust)
Manual editing (point, transect, area, etc.) must be
done elsewhere (generally in a GIS)
A software package was needed that provided all
of these tools in one place

Yield Editor
version 2.0

In 2010 we began developing a new version of
Yield Editor that would automate more of the yield
data cleaning process
 Delay
time
 Overlapped travel at end rows and partial swaths
 Unrealistic point yield values
 “Smart” thresholds for other filtering parameters
 Batch mode operation
