The idea was to develop a simple classification procedure, usable in various contexts and requiring little training to be used by non-experts. We also rationalized errors of omission by applying simple buffer boundaries around knotweed predictions to know if heterogeneity across multi-date images could lead to unfairly harsh accuracy assessment and, therefore, ill-advised decisions. Although our crisp satellite results were rather average, our UAV classifications achieved high detection accuracies. Additionally, the buffer boundary results showed detection rates often exceeding 90–95% for both satellite and UAV images, suggesting that classical accuracy assessments were overly conservative.
