query_type = linear means that the values at a point on the surface are 
interpolated using the values in the spatial database.

If query_type = nearest is getting you closer to what you want, it 
suggests that the points you are providing have the wrong spatial layout 
or the coordinate system is inconsistent with the coordinates of the points.

If you can give us more detail than "it didn't work" like the exact 
error message or more detail of what happened, we may be able to 
pinpoint the problem.
