Supervised Classification- reclassify errors

Question asked by geogalusa on Oct 31, 2018

Classify the imagery—Calculate Impervious Surfaces from Spectral Imagery | ArcGIS I'm working on this Supervised classification lab on the web site.  In the "Reclassify Errors" step 4 section, I finished the classification wizard, when I wasn't finished yet.  Can you go back to the "reclassify the errors" or an earlier step in the classification wizard section, or do you  need to start the entire process all over again (i.e. creating training sites)?  I can't figure out where to restart.
