Can you share the geotiff image somewhere? The question is are the raster references going to be in latitude, longitude or are they in Easting, Northing values? Can you list out the info that you get from executing:
info = geotiffinfo(fullfile(iDir,filename));
Or the contents of R when you execute:
[data,R] = geotiffread(fullfile(iDir,filename));
