I'm attempting to make a flood plain map for a school project, and am using FEMA Flood Hazard Symbology for the legend. I've dissolved by a Flood Zone Field, but am left with two attributes both named "X" they are slightly different, but for what I need it does not matter.
I want to consolidate these attributes into one. So far I've tried to merge them using the editor toolbar. The process starts to run, but ArcMap locks up and eventually says the merge cannot be completed: Not enough memory. I'm running Arc on a computer with 8Gb or RAM. Is there another way to consolidate these into one, or a way to not make it lock up?
