[visad] plotting h5 image in visAD

Hi,

    I managed to get Latitude,Longitude,and RH1 array from a h5 image.
But I am confused how to plot it on visAd.

I have set the flatfield by  the range data (rh1 data) but how to convert
Latitude and Longitude arrays into realTypes.

My mathType is : (Latitude,Longitude) --> (RH1)
