Is it possible to obtain flow accumulation from negative elevations

by Shannon Richardson   Last Updated January 11, 2019 10:22 AM

I have bathymetric data extracted from INFOMAR ArcGIS grids.

Based on the data I am wondering if the fill, flow direction and flow accumulation tools work with negative elevations or if I have to use the raster calculator to change them to values lying above the sea level.
