GPS Auto-Steer Swath Control Simulator (2D Field Map)

Precision agriculture starts on the ground, with the guidance system that keeps a sprayer, planter or spreader on its planned line pass after pass. This 2D top-down simulator drives a virtual implement across a rasterised field using a mean-reverting cross-track-error model tuned to three real guidance tiers — manual steering, WAAS-corrected GPS, and RTK GPS auto-steer — and rasterises the resulting swaths cell by cell to show exactly where passes overlap (wasted double-dosed input) and where they leave gaps (skipped, untreated ground). A live drift-trace chart plots the same cross-track-error signal driving the field map beneath it. Pan and zoom the field, switch guidance modes, implement width, travel speed and field width to see how each one trades off coverage efficiency, and watch the live overlap, skip and input-waste percentages settle as the tractor works its way across the field.
