Residue spread mapping

Abstract

Systems and methods for mapping the distribution of residue material in an environment in which one or more agricultural machines are operable. A sensing arrangement having one or more sensors mounted or otherwise coupled to an agricultural machine operating within the environment is used to obtain sensor data indicative of residue material spread by a spreader tool of the agricultural machine. From this a local distribution of residue material associated with the spreader tool is determined which is used to update a map of a global distribution of the residue material across the environment. The map comprises a grid-based map having a plurality of cells corresponding to sub-regions within the environment, wherein a value associated with each cell is representative of a measure of the residue material present within the corresponding sub-region.
