Hi all, I have two geotiff images about same scene but they have a different tag "Model Type": in one of them this tag is MODELTYPEGEOGRAPHIC and in other one is MODELTYPEPROJECTED. Is possible to change from ModelTypeGeographic to ModelTypeProjected? Thanks in advance

You can use the function geotiffread to obtain the spatial referencing object, R from a geotiff image. This object is different for ModelType: Geographic and ModelType: Projected. You can then use geotiffwrite together with the referencing object obtained from one type of geotiff image to write the second geotiff image in the same modeltype. However, in order to make sure that this conversion is valid, I would like to test it on the images that you are working on. If possible, post your images here, so that I can verify that this method works correctly.
