Hi everybody,
I am new in Matlab,using hdf5-1.8.8 data given from INSAT-3D satellite. Using Matlab R2009b, I have calculated Latitude, longitude and Brightness-temperature like this
Latitude =hdf5read('3DIMG_01JAN2014_0001_L1B_STD.h5','/ Latitude /');
Longitude =hdf5read('3DIMG_01JAN2014_0001_L1B_STD.h5','/Longitude/');
temp =hdf5read('3DIMG_01JAN2014_0001_L1B_STD.h5','IMG_TIR1_TEMP');
but ‘latitude’ and ‘longitude’ dimension is 2805x2816 int16 whereas ‘temp’ is 1024x1 single. How can I make ‘temp’ dimension 2805x2816 int16.I want to make spatial plot of latitude, longitude and Rain in Indian region.
Please help

It looks like 'temp' is not the right variable to use here and is used for calibration purposes. From the manual it seems that TSurfPhy or TSurfReg would be a better choice (but I haven't read the manual completely, that is for you :)).

See the units of latitude and logitude.
See in which projection it is.
Then use
