I have a DEM, 3d matrix with elevation coordinates depending on the xy location. I would like to create a plot (or matrix it doesn't really matter) of the coastline. The goal is to plot temperature of the area with the coastline on top of it.
I tried the different 'contour' functions but they all give me horrible results. I thought to use the imcontour function, but then I lose the 330x300 dimension of the matrix when I save the image.
Does somebody have any idea about what I could do to create this contour plot ?
Have a nice day and thank you !
