; Open the Jagwire Server
jagwireServer = ENVIJagwireServer('https://myserver/jagwire', $
  USERNAME='myusername', PASSWORD='mypassword')
 
; Get a list of rasters within Florida
listings = jagwireServer.Query(Hash('bbox',[-88.0, 24.0, -79.0, 31.0]))  ;xmin, ymin, xmax, ymax
 
; Get metadata from one of the listings
metadata = jagwireServer.QueryDataset(listings['datasetName'])
 
; View the dataset properties
print, metadata

Syntax


Result = ENVIJagwireServer.QueryDataset(URI [, Keywords=value])

Return Value


This method returns a hash table of key-value pairs of metadata that are available in the Jagwire server.

Arguments


URI

A scalar string denoting the fully qualified URL path to the Jagwire OGC WCS dataset.

Keywords


ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
