I have been working with multispectral and RGB orthomosaic imagery in ArcMap 10.5. I was wondering if anyone knew of a way to possibly automatically have shapefiles drawn around specific objects within the imagery. Doing it manually is great and all but very time consuming for large areas. Maybe there is some python scripting that can be done but, that is a little out of my expertise. I have attached an image as an example. The yellow shapefiles around the objects (2) were done manually and the goal is to make this automatically for similar objects in the imagery. Hope to hear from someone, any information would be greatly appreciated.
