I am trying to create a spatial model to generate drainage network in GeoMedia Professional.
I am found some Grid Analysis operators like - Fill Depressions, Calculate Flow & Accumulate Flow. By using these operators, I am able to generate Drainage Network in Raster format.
I want vector feature for this drainage network using spatial model.

Raster Input > Convert to Features > Smooth Geometry > Create Skeleton > Features Output
Raster Input (This is your Rivers, make background NoData if not already) ie Rivers.tif
Convert to Features (This will create polygon feature around river pixels)
Smooth Geometry ( This is optional, use if raster pixel size is course to smooth polygon edges)
Create skeleton (This will create river centreline features inside polygon)
Features Output (Save river features)
