Hi Eric:It is unclear if what you are asking is that you only want the TDS to display a subset of the data to the user, or if you want to know how a user can subset the data that is being served by the TDS. If the latter, what applications do you use or do you just want to use the hrml page.
Either way, is the TDS publicly accessible? Thanks, -Roy M. On Jan 7, 2008, at 4:04 PM, Eric Davies wrote:
I've got the Thredds Data Server installed and I'm trying to use it to subset a 3D grid (depth, latitude, longitude) large netcdf file. The netcdf file was generated by a third parties software, and is probably not compliant with anything. As subset of its schema is shown below.If I rename some coordinate variables, I should be able to make it compliant with some convention. My question is how do I most efficiently extract a 3D subset? I want to extract a subset of depth as well as a subset of longitude and latitude.Any ideas would be most appreciated. Thank you.
