Contour plot comparison What are the ways to compare two different maps? I was thinking of taking the matrices of each map and then quantify their spatial differences by plotting the map of the differences of the two matrices. Are there any other ways? I'm fairly new to this.
EDIT: It should be known that I have access to all the data in order to plot those maps but I’m not very familiar with cross validation or statistics, that’s why I’m addressing the question here.


Plotting the contours side by side is still effective for visual comparison, however, ensure that the colourmap axes are the same, otherwise it's not a good comparison.
Other than that, plotting the differences seems appropriate and a contour map will highlight areas of large differences etc.
