WebMar 26, 2024 · I'm doing research on 'Automated Building Extraction'. I have 3D point data for an urban region with no vegetation and ground points. Now the points I have is mostly on building roof. WebJun 5, 2012 · It looks like griddata might be what you want. The link has an example in it. If this doesn't work, maybe check out gridfit on the MATLAB File Exchange. It's made to match a more general case than griddata.. You probably don't want to be rolling your own surface fitting, as there's several well-documented tools out there.
