sample_map.fig

Hello, I made a map from latitude (X), longitude (Y), and elevation (Z) data. Unfortunately, I can't find the original data that I used. However I do have the matlab figure. How can I extract the X, Y, and Z data from the Matlab fig file?

Attached is the matlab fig file I would like to extract the data from.

Something like this:

                              F = openfig('sample_map.fig');
                             
                              h = findobj(F,'type','surface');
                             
                              x=get(h,'xdata');
                             
                              y=get(h,'ydata');
                             
                              z=get(h,'zdata');

That's assuming you're after the surface plot data. If there are other objects in the axes which have data you need, you'll have to find them too.

                                   x=get(h,'xdata');
                                  
                                   y=get(h,'ydata');
                                  
                                   z=get(h,cdata的);
