Hi Kyle:
This is a problem with 2D Coordinate Systems eg lat(x,y), lon(x,y).
Currently the code does not know how to find the index point (i,j) given
a (lat, lon) coordinate, which is what the "Grid as Point" function needs.
I am working on a fix for this, thanks for reporting the problem....

Hello all,
I have a dataset that works correctly with the grid subset, ncWMS, and
any other NetCDF tool I can come across. It is failing with the
THREDDS NetCDF subset when requesting point data.
Dataset:
http://staging.asascience.com:8989/thredds/catalog/Cadiz/Currents/catalog.html?dataset=Cadiz/Currents/EGM200_3.nc
Point Subset:

Is this most likely caused by an incorrect dataset?
