I have several ArcGIS grids of bathymetric data extracted from INFOMAR in 5m resolution, I have merged them into one layer but when I go to conduct the hydrological analysis it says it is conducting it for hours and then ArcGIS stops responding after then, anyone have any suggestions ?

  • You need to provide much more information for anyone to help. Size of final raster, raster format, integer or float? Where are you are storing it? What are your machine specs? Currently your questions is a bit like saying "my car stopped working, do you know why?", Of cause our first response would be something like have you tried putting the key in it... Please amend your question and add more information. – Hornbydd Jan 11 at 12:32
