The Data (Constrained)
Data are requested with a URL.
- The structure of the data is defined by the DDS.
- The user can impose a constraint on the data that s/he would like
to acquire from a data set by appending a constraint expression
to the end of the URL. For the example under discussion, the
constraint is: sea_level[215:1:296][532:1:719] and follows a "?".
- Data for a data set may be requested from the browser by appending
.asc to the data set name prior to the
constraint. This is a server-side service.
The URL for the constrained request described above is:
http://dods.gso.uri.edu/cgi-bin/nph-nc/WOCE2000/SeaSurfaceHeight/topex/data/05_deg/ssh05d19950414.nc.asc?sea_level[215:1:296][532:1:719]
