I'm using Google Earth Engine to map Center-pivot Irrigation using Satellite data. My dataset consists of spectral data (reflectance data like visible, near infrared etc..), but that can only help differentiate soil from vegetation. I extracted some spatial attributes (area, diameter,.., elliptical fit) to help me map circular shapes, but I'm having trouble with that a little and need your guidance with that. What I did so far is a pixel based classification using spectral input, but that is not enough as we need the spatial/physical attribute here. can you please help me with that?
