A lower-level function for calculating a cell area matrix (2D array) from an elevation matrix. The area is based on the surface area of the terrain in the cell. The area matrix is then used in calculating areas of 2.5D MKDES.
A 2D array with elevation values.
Size of the cells. It is assumed to be the same in the x and y dimensions.
This is a wrapper function for C++ function that calculates the surface area of each raster cell given the cell elevations. It is not intended to be used directly; instead, the user should call
initializeAreaRaster on an MKDE object.
A 2D matrix of cell surface areas.
