I am trying to delineate catchments based on a flow direction grid.  Some of the points I am using to delineate catchments fall on the same grid cell.  I am looking for a way to identify these points.  Is there a way to attribute each point with a unique identifier representing the grid cell it falls on?  Or is there a way to convert the raster to a polygon where each cell is a separate feature?
