I#m trying to figure out how to work with tif files in Matlab. I tried following this example:

https://de.mathworks.com/help/map/ref/readgeoraster.html

But when I try executing this code:

(Data from https://land.copernicus.eu/pan-european/corine-land-cover/clc-2006?tab=mapview )

[A,R,cmap] = readgeoraster('U2012_CLC2006_V2020_20u1.tif');
geoshow(A,cmap,R)

I get this Error Message
