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

[Purvis, Charlton]

Yeah, Gerry.  That's what we use around here.  Going from SSH track data
into smooth contours fits most closely w/ your query, I think.  Create a
timestamped grid based on sparse x,y data that's inside PostGIS.  Run GMT to
produce the contours based on your current extents and time.  Shove the
resultant image and .wld back up to MapServer for the final product.
 
And thanks for the promo spot, Paul, re. large datasets!  ;)

<sound of slapping head with board> 
I should have thought about that.  GMT's got all the tools directly.

Thanks, Brent.
