The spatial and temporal persistence of weed patches is very difficult to describe without visual information. Predominantly, geographical information systems (GIS) and geostatistical methods are applied in order to describe the patchy nature of weeds in arable fields or to calculate correlations between different time series of weed maps. Additionally, it is imperative to gather information concerning the persistence of weed patches because the money and resource-saving effects of site-specific weed control can only be validated on the basis of information about the reduction or increase of the area of weed patches in arable fields. In this study, a vector based approach, analysing the shapes (contour lines) of weed patches generated according to a specific weed threshold is demonstrated.
