Training samples (identifying based on orthophoto)

Question asked by Piskota on Apr 8, 2020

Hi guys,

I wanted to identify "private plots, gardens" (like in picture) based on orthophoto.


I thought about training samples, but it results wrong of course, because of the all the colors which were included in samples, result was whole orthophoto.


I have a ArcMap 10.4.

I have also polygons representing many fields but it would take me a lifetime to go through it manually.


Do you have some idea please? Is there any solution for making this searching/identifying automatic (perhaps semi-automatic)?


Thank you very much.
