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

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
