Hello,
I got daily sea ice concentration data from https://nsidc.org/data/G02135/versions/3(please see attachment), but the file is in geotiff format, and I don’t know about geotiff format. I don't know how to get sea ice concentration data corresponding to longitude and latitude from geotiff?
Hope to get your help! Thank you very much!
Bei.

filename = 'N_20180101_concentration_v3.0.tif' ;
[A,R] = readgeoraster(filename) ; % If not try geotiffread
[m,n] = size(A) ;
x = linspace(R.XWorldLimits(1),R.XIntrinsicLimits(2),n) ;
y = linspace(R.YWorldLimits(1),R.YIntrinsicLimits(2),m) ;
[X,Y] = meshgrid(x,y) ;
figure(1)
mapshow(A,R)
figure(2)
pcolor(X,Y,A);
shading interp ;
