The Spatial Low-Pass Filtering as an Alternative to Interpolation Methods in the Generation of Combine Harvester Yield MapsPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Applied Engineering in Agriculture. 27(6): 1087-1097. (doi: 10.13031/2013.40612) @2011Authors: J. Gómez-Gil, L. J. López-López, L. M. Navas-Gracia, G. Ruiz-Ruiz Keywords: Key words Precision agriculture, Yield mapping, Filtering, Interpolation, Mass flow sensor Interpolation techniques are usually employed in the yield maps generation. In this article, a method based in spatial low-pass filtering is presented and compared with interpolation techniques. The method consists in the application of low-pass filters typically used for image processing. The yield map is constructed in a similar way to a Digital Elevation Model (DEM), except for the fact that heights represent crop quantities. (Download PDF) (Export to EndNotes)
