Mapping invasive weeds using remote sensing requires matching sensor and platform requirements to the weed's biological traits. there are a wide variey of aircraftand satellite data available, which differ in spectral resolution (number of bands), spatial resolution (pixel size), temporal resolution (repeat frequency, if applicable), and cost (low cost to expensive). There are four major methods to detect invasive weed: the air of interpretation, supervised classification, unsupervised classification, and feature analysis. Error assessment is a critical element of weed mapping, and requires detailed data collection and analysis.
