Raster to segments

Algorithm

First, the Raster to segments operation finds areas of pixels in the input map that have the same class name, ID or value. Areas can be constructed from pixels that are either horizontally or vertically connected (4-connected) or horizontally, vertically or diagonally connected (8-connected). For more information on constructing areas of 4 or 8-connected pixels, see Area numbering : functionality.

Then, from the boundaries of these areas, segments are extracted.

Finally, if specified, the segments in the output map will be smoothed.
