I am trying to create streams and outlets in APEX Subarea Delineation (version 10.3.1). I checked the DEM projection set-up and projection of all files (DEM, channels, delineation): Geographic coordinate system: GCS_North_America_1983 and unit: meter. I followed the steps (step 1-4) of subarea delineation in ArcAPEX manual. In steam definition, I chose pre-defined steams and watershed and I insert delineation .shp in watershed dataset and channels .shp in steam dataset. Then tried to create steams and outlets in steam network option. I got an error message – this is indicated in the attachment, please find.
Can you please help me to find out the error and creating steams network? Thanks in advance for your kind help.
With regards,
Ratnajit
