Description
No ocean areas were detected by the tool. This can occur when generating an ocean mask from a DEM when the input raster does not contain any ocean areas. In this case, the tool will create a raster identical to the input raster.
Solution
Confirm that the input raster overlaps with ocean areas. If no ocean area is expected, the warning can be ignored. Otherwise, review the input data and parameters to ensure that the input raster covers the intended coastal or ocean areas.
