Hello everyone! So i was trying to create a image interpretation key for this picture: https://imgur.com/gallery/pbs31lQ sadly i haven´t understood the image interpretation keys so good, and on internet i couldn´t find a concrete example. Could anyone create a image interpretation key for the following classes: Meadow, Agriculture, House / building, Road and this criteria: colour, texture, structure, size, shape and context for each of them. It would help me alot at understanding how the image interpretation key construction exactly works. Thanks.
