To John Caron,
So the station and trajectory features of the java netcdf library are
coming on line. Is there now, or will there be, a way to get subsets of
the data (equivalent to the subsetting methods like
StationDatasetHelper.getStations(boundingBox, cancel) and
StationDatasetHelper.getStationObs(boundingBox, startTime, endTime,
cancel) via opendap?
we are currently investigating hooking opendap sequences (eg dapper) into the
station dataset API. The answer is probably yes, for those opendap datasets
that support lat/lon constraint expressions.
And can you confirm that opendap for netcdf probably won't support
constraint expressions for these point dataset .nc files (which would be
another way to accomplish the same goal)?
Is there, or will there be, any way to subset point dataset .nc files
via opendap (short of the client reading all of the data and subsetting
it)?
so now this is a server question, so i will answer in context of TDS. We will provide that functionality (for netcdf files we know how to read into a station/point/trajectory obs dataset) through a web service one way or another. _Probably_ also through opendap sequences, but its still an open question. We really want to provide just a subset of the functionality that sequences have.
What needs do you specifically have?
