Hi i have two question: - When i use geotiffread for satellite image georeference's how can i have access to it's spatial references to be able to compare them with an other satellite image of the same place but with a different field ?
- For sentinel 2 image i have or a XML file or all the seperate bands in jp2 in this case how can i have acess to the spatial references ? Thanks very much for your answer.

According to the documentation geotiffread returns a spatial referencing object of the file.
[boston, R] = geotiffread('boston.tif');
Here, R contains the spatial reference object.
R =
MapCellsReference with properties:

YWorldLimits: [2951122.28480912 2960574.36564245]

Thanks for your answer,
Is there a possibility to also open Sentinel 2 images with geotiffread or in another way to get MapCellsReference.
The Sentinel 2 fields are:
