I add geologic maps for individual states as klm files downloaded from the USGS website using the "Add Data" icon.
The imported klm files show in the CONTENTS panel under a single line e.g.: "Geologic Units of Maine", with dozens of geologic units listed individually underneath. The individual units show as polygons on the map. I need to change the symbology (color, pattern, etc.) of individual geologic units in the content panel and map.
Please advise,
