TimeStride for NCSS point

Open dopplershift opened this issue 8 years ago • 1 comments

From esupport ticket WML-374203:

This is a request to please add support for the "timeStride" parameter for
Point Datasets served via NetCDF Subset Service (NCSS) in TDS. As your
documentation
<http://www.unidata.ucar.edu/software/thredds/current/tds/reference/NetcdfSubsetServiceReference.html>
states online, this is currently only available for Grid Datasets. It is a
nice feature when one needs to make a long time series plot without
drinking from the fire hose! :) In particular, I would like to use this for
dynamic online plotting for our various FMRC model outputs. While these are
Grid Datasets, I am querying them at a specific lat/lon point and using the
"Grid as Point Dataset" feature inside NCSS. I tried adding the timeStride
parameter to one of these URLs as a test and it does not perform any
temporal stride.

Here is an example that shows three months of hourly wave heights on Oahu
at a lat/lon point. Note I have set timeStride=100 but am still getting the
hourly results:

http://oos.soest.hawaii.edu/thredds/ncss/hioos/model/wav/swan/oahu/SWAN_Oahu_Regional_Wave_Model_best.ncd?var=shgt&latitude=21.7&longitude=-157.7&time_start=2015-10-01T00%3A00%3A00Z&time_end=2016-01-01T00%3A00%3A00Z&vertCoord=&accept=csv&timeStride=100

It would be great if a future version of TDS could support this. Thanks for
listening!
