    %% Construct Referencing Object with Raster Interpration of Cells

%%
% Define latitude and longitude limits and dimensions of the image. The
% image follows the popular convention in which world _x_ coordinates
% increase from column to column and world _y_ coordinates decrease from
% row to row.
