The accuracy usually stated in the GOS specs are the horizontal uncertainties, the vertical uncertainties are much higher.  You can get sub-meter vertical accuracy with additional GPS units and some pretty intense processing, but not with a signal GPS receiver.

This type of surveying does not require vertical accuracy. The 2d data can be easily draped over a typical topo survey.

The point is, though, that this kind of survey could also be set up to take interval readings for a grid without gps. We don't need to get bogged down with gps accuracy.
