Hi! Great video but why do you change the cell size to 90? I'm working with 30m cell size and mine says 31; should I resample to 30? What would be the benefits?

Choose a band combination for the classification that works best for picking the mangrove. You may set some classification error that you can edit manually.

I would like to ask - why I receive slightly different results for OBIA by shapes and OBIA by grids? - I defined five training signatures - in "shape version of OBIA" I received an assignment of all segments to my five categories - in "grid version of OBIA" I received six categories - one category contained segments that were not assigned to my signatures - why - is it not same algorithm, method?

@rohitkumarGIS 4 жыл бұрын
I can try to answer. In grid you may have adjacent pixel value while in shape one tries to create precisely boundary. Statistically this would change the result a bit. hope it satisfies.
