I am trying to follow this example:
https://www.mathworks.com/help/map/ref/geotiffread.html
with a GeoTIFF from:
https://neo.sci.gsfc.nasa.gov/view.php?datasetId=MODAL2_D_CLD_FR&date=2017-03-01
However, when I use this code:
[A, R] = geotiffread('MODAL2_D_CLD_FR_2017-01-01_rgb_3600x1800.tiff');
and then try to plot with:
mapshow(A, R)
I get a string of errors:
_Error using checkRefObj (line 25) Function mapshow expected input number 2, R, to be either a 3-by-2 referencing matrix or a scalar map raster reference object. Instead its size was 256x3.
Error in validateMapRasterData>parseImageInputs (line 112) refmat = checkRefObj(mapfcnname, R, size(A), R_position);
Error in validateMapRasterData>validateImageComponent (line 92) [A, R] = parseImageInputs(mapfcnname, dataArgs{:}, cmap, rules );
Error in validateMapRasterData (line 26) [Z, SpatialRef] = validateImageComponent(mapfcnname, ...
Error in maprastershow (line 127) validateMapRasterData('mapshow', dataArgs, displayType, HGpairs);
Error in mapshow (line 228) h = showFcn(varargin{:});_
Any thoughts?

Did you solve the problem?
I am facing same issue as after loading tiff file mapshow is showing following error.
Thanks in Advance
Error using checkRefObj (line 25)

How are you downloading the GeoTIFF file from the below site?
https://neo.sci.gsfc.nasa.gov/view.php?datasetId=MODAL2_D_CLD_FR&date=2017-03-01

There are two types of tiffs, a floating point and a raster, on that site. I found out I need to load one for A and the other for R to get A in uint8 and R in the right format. Cumbersome, but now I got it to plot.
