WebbSupervised classification uses observed data to teach an algorithm which combinations of red, green, and blue light (pixel values in an image) represent grass, trees, dirt, pavement, etc. Unsupervised classification assigns pixels to groups based on each pixel’s similarity to other pixels (no truth, or observed, data are required). Webb15 mars 2024 · First, cloud-free Landsat images were derived from a single image or a composited annual pixel value. The image was used to select training points based on investigator knowledge for five LUC classes: peat swamp forest, tall shrubs/ secondary forest, low shrubs/ferns/grass, urban/bare land/open flooded areas, and river (see …
