Change only coordinates of a georeferenced tif file from utm to degree

6 views (last 30 days)
I want to open a bathymetry as tif file and only changed the UtM coordinates into degree. The problem is that in info are important information for the tif and I don't know how to put this information in geotiffwrite. So the new tif file changed more than only the coordinate transformation. Is it possible to change only the coordinates?

Code:
infilename = 'helgoland_bathy.tif';
[A,R] = readgeoraster(infilename);
info = geotiffinfo(infilename);
geoTags = info.GeoTIFFTags.GeoKeyDirectoryTag;
x =R.XWorldLimits;
y=R.YWorldLimits;
utmzone=['32 U';'32 U'];
[LatN, LonN]=utm2deg(x,y,utmzone);
R.XWorldLimits = LonN';
R.YWorldLimits =LatN';
geotiffwrite('testtiforiginal_grad.tif',A,R,'GeoKeyDirectoryTag',geoTags);

You may use the following file exchange function to convert utm to degree.

ok but how can i write all information from the old tiff to the new one. Also the infromation in the info variable? Something like this:
infilename = 'helgoland_bathy.tif';
[A,R] = readgeoraster(infilename);
info = geotiffinfo(infilename);
geoTags = info.GeoTIFFTags.GeoKeyDirectoryTag;
x =R.XWorldLimits;
y=R.YWorldLimits;
utmzone=['32 U';'32 U'];
[LatN, LonN]=utm2deg(x,y,utmzone);
R.XWorldLimits = LonN';
R.YWorldLimits =LatN';
geotiffwrite('testtiforiginal_grad.tif',A,R,info);
