Hello Aswathi,
I understand that you want to extract latitude and longitude from geotiff file in Matlab R2019a. For achieving this, you can use the following workaround :
[A,R] = readgeoraster('inputFile.tif');
[x,y] = pixcenters(R, size(A), 'makegrid');
info = geotiffinfo('inputFile.tif');
[lat,lon] = projinv(info,x,y);
figure
geoshow(lat,lon,A);
xlabel('Longitude (degrees)')
ylabel('Latitude (degrees)')
Moreover, to fit the figure's axes to exactly match the size of the geotiff file, use the following code in addition to the above snippet :
xlimits = R.XWorldLimits;
ylimits = R.YWorldLimits;
[latlim,lonlim] = projinv(info,xlimits,ylimits); % if using 2021a or later, use 'R.ProjectedCRS' instead of 'info'
xlim(lonlim);
ylim(latlim);
I hope this helps!
