Hello everyone, first post!

I have a question. I am trying to symbolize my data based on multiple fields in the layer. The best way I can describe this is with an example.

Lets say that I was attributing river widths in my data and everytime I drew a river and coded it with a width the river would turn blue upon finish. However if I didn't attribute the width field then the river would turn red (so I knew I had to code that). Taking that one step further if the river was coded with a true/false tributary field and that wasnt coded then it would turn red however it would turn dark blue if true and light blue if false.

I hope that makes sense, its the best way I know how to describe what I am trying to achieve.

Thanks for all of your help!

Hi Cobalt - what software are you doing this in? I suspect it is ArcGIS - right? If so, look at "multiple attributes" when symbolizing a layer...

Thanks for the quick response Frax,

I am using ArcGIS 10. Does this change your guidance at all?

Thanks again for your time

Cobalt - isn't "multiple attributes" in the symbology dialog what you are looking for?
