Panchromatic, multispectral and color very high spatial resolution aerial photography (1947 to 2006, res. 0.5 m), and medium spatial resolution satellite data (Rapid Eye 2010, res. 5 m) were analyzed to assess their potential for hogweed monitoring by using pixel- and object-based image analysis. We established automatic, relatively fast, and efficient (time-effective and standardized) computer-assisted methods for monitoring invasions and their long-term dynamics that could be applied over large areas. The methodology presented here is suitable for mapping the progress of invasion, identifying areas at the highest invasion risk, and enabling early detection at the beginning of invasion, hence it can make management measures more efficient and less expensive.
