I have a bunch of data symbolized by categories - unique values. I have grouped together many (10 to 40 per grouping) different values to create this symbology. Now I need to figure out the total areas contained within these symbology classes I have created.
For example: I created a symbol value called 'Residential' by combining features with the attributes mobile home, labor camp, condo, apartment, duplex...and many more.
Now I need to know the total area in the 'Residential' symbol value I have created.
Is there any way to do this without going back to all the disparate classes (mobile home, labor camp, condo, etc etc) and summing them up first? (massive time sink)
It seems like a simple task since I can see the areas I need to quantify symbolized on the screen.
