[postgis-users] Has anyone considered interpolation of sparse point networks?

[Gerry Creager N5JXS]

I'm getting a dataset on a daily basis that we're putting into PostGIS. 
  It's a triangulated irregular network (although others will be 
quadrilateral irregular networks, or irregular polygons) with a scalar 
at the vertices.

I will be saving these in PostGIS, and as part of the visualization 
process (I'll also post appropriate questions toward the Mapserver list) 
we're going to need to interpolate to create a processed, synthetic 
dataset of contours.

This seems like it should be straightforward, but I'm having a little 
trouble organizing a strategy and getting started.

Has anyone else looked at this sort of problem and done something similar?

Thanks,
Gerry
