Hi all,
I want to ask if anyone knows why the Hydro Area feature class got new features after running Generate Product Layout GP tool or Cartogrpahy-Automated workflow.
Initially, the Hydrography surface feature class did not have features in the specified area since there are islands covered by the Physiography surface feature class.
(I just turned on the hydrographysurfaces - withoutOutlines feature layer to show that there are no river subtype features.)
However, those empty areas turned into the EGB_HYDRO_A features when I ran the GPL tool or Cartography-Automated workflow through the workflow manager, and displayed like the picture.
I want to keep those areas empty so that they can show the white background. What shall I do to fix this?
Thank you.
