Mark,
     Sorry for taking so long to recheck this support ticket.
     I think the missing value might relates to the sampling mode you selected, 
the weight average. If you select the nearest neighbor mode, you should get the 
correct value. For the 2D dataset, you can ignore the altitude value as it has 
no meaning, but the IDV display is in 3D mode.
