Your spatialdb file for z+ isn't complete.  It should be in such a way that when the spatial data is queried at any location on the boundary, a value should be found.  In specifying "nearest", you can simply specify at any one point and nearest will interpolate the value to be exact same as the value specified for the entire boundary as that is the only available point.  "Linear" interpolation, on the other hand, requires one value to be specified at each of the edges or the spatialdb file should enclose the span of the boundary.
