Replace the values less than zero by NaNs, then use the surf command. Something like the following perhaps:

ix = WH<0;
WH(ix) = NaN;
surf(WH), view(0,90)

Remove the view(0,90) command if you want a 3d view.

when I plot them some point are in ocean and other are missing in some part of land. still there some issues

I guess you have to decide what elevations constitute land, then replace all other values by NaNs before plotting.
