I have extracted a TIFF image into Matlab using the geotiff function [A, R] = geotiffread(filename). Now the image is stored for example in A. I want to extract the X,Y and Z coordinates from this image and plot it later using surf function. How do I achieve this?
Thanks for any inputs or pointers

Here are the x and y coordinates of a geotiff:
I = geotiffinfo(filename);
[x,y]=pixcenters(I);
2022 Update - The function pixcenters will be removed in a future release. Use the worldGrid functions instead.
