A solution to this is discussed on the ESRI forum here: Every planar surface has a simple formula, Jesse, in the form (something)*x + (something else)*y + (constant). In the Raster Calculator, x is $$XMap and y is $$YMap. The trick is figuring out the coefficients. Often you want to specify a plane in terms of its slope (s), aspect (a), ...

It will depend on the type of information you have in the satellite image i.e. RGB (Red Green Blue) values or GRID type (value as in DEM). If you try to convert, to integer, a raster image in RGB format is very possible to get the value 0. However, if you convert the values ​​by classifying them into a series of numerical codes representing a scale of ...
