Hey there. I am a complete beginner with ArcGIS. And when it comes to raster I will not even get started :).

I have a raster layer made up of 8 distinct parcels of land.

Managed to assign 3 different color values which apply to the parcel. These values are slope %. (A=0-1%,B= 1-3%,C= 3%+)

I am attempting to calculate what percentage of each make up each of the 8 distinct parcels. For each of them separately.

If possible I would also like to calculate number of A which are connected together and B which are connected together.

Thank you guys so very much.
