High-Resolution Imagery Data: Color-infrared digitalaerial image data with a pixel size of 0.6m acquiredin 2004 were used in this letter for comparison purposes(Fig. 2). The imagery was 3-band color-infrared, with green(510–600 nm), red (600–700 nm), and near-infrared bands(800–900 nm). The imagery data has an 8-bit radiometricdepth, and was orthorectified [2].
