This is only for 2D surface area. For 3D surface area (that is the surface from reality), it will be higher values. Unfortunately ArcGIS cannot calculate that. I'm right??
Yeah, it is very accurately and you should know that the surface that you will get while using slope will be different to that one that you will get using the normal boundary of your AOI.
@@ernestruzindana8286 this is what I have been searching for to accurately the area considering its slope. I thank you ones again for sharing this technique. 👍👍
