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?
@trowertower3 жыл бұрын
Good question. When I originally made this tutorial only 3second DEM was available so I resampled to 90 meters

Also at that resolution the process runs quickly on any computer

Thank you for the excellent tutorial. I wonder, why do you prefer the RGB band combination instead of false-color composite for Mangrove (4811)? Does it make any difference if I use the latter band combination? Thanks in advance.
@trowertower3 жыл бұрын
No it shouldn't make a big difference. Try and see.

how do you differentiate between mangrove and any other vegetation so the computer won't confused which mangrove and which is another vegetation? im following your tutorial step by step by the way
@trowertower4 жыл бұрын
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?
@rohitkumarGIS4 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.
