[postgis-users] Clarification on an error ("Coordinate does not overlap grid extent:")

[Gregory S. Williamson]

We have recently upgraded a runtime server from 7.4 / postGIS 0.8 to POSTGIS="1.1.1" GEOS="2.2.1-CAPI-1.0.1" PROJ="Rel. 4.4.9, 29 Oct 2004" ... overall we are seeing lots fewer errors and a happier overall experience, but also a new error which I am not easily comprehending (copy of the log):

ElevationMatrix::add((-96.5,40.7889,40.7889)): Coordinate does not overlap grid extent: IllegalArgumentException: ElevationMatrix::getCell got a Coordinate out of grid extent (Env[-96.538:-96.4822,40.7371:40.7731]) - cols:3 rows:3

Can anyone suggest things I might try to investigate this ?

Thanks (and double thanks to the postGIS developers for the many improvements to this nifty package),
