AddToWatershed

Adds pixels to an existing watershed. This transform resolves pixels that are in sinks and flat areas until all the pixels in the raster are within a watershed. Note that pour points should be provided for all watersheds to make sure the sinks flow to the correct watershed. If a watershed is missing a pour point, it's pixels will flow into an adjacent watershed.

Watershed Raster : This is the initial watershed raster typically from the "Find Iniitial Watershed Raster" transform. The pixels in the watershed raster have the following values:

• 0 - Pixel that is not in a watershed
• >0 - Identification number for that watershed

Directions: The initial direction raster. Note that this raster will be modified to indicate the direction of flow for pixels that are in sinks or flat areas.

DEM:The raster with elevation values.
