This function returns a value of 1 if a catalog path (supplied as an argument) points to an an ArcGIS geodatabase, and it returns a value of 0 otherwise.

Syntax

---

value = ENVI_IS_GDB(CatalogPath, [GDB_TYPE=variable])

Arguments

---

CatalogPath

A catalog path is one that ArcGIS recognizes; it includes the name of the geodatabase plus a raster dataset within the geodatabase. Set CatalogPath to a string value. Following are some examples of valid catalog paths.

ArcGIS File geodatabase:

Local: 'C:\data\core\CoreGeodatabase10.gdb\S068W013d_Clip'

Universal Naming Convention (UNC) path: '\\ags10\data\CoreGeodatabase10.gdb\S068W013d_clip'

ArcGIS Enterprise geodatabase:

ArcCatalog: 'Database Connections\ags10-sde.sde\sde.sde.s068w013d_Clip'

Local: 'C:\Documents and Settings\user\Application Data\Esri\Desktop10.0\ArcCatalog\ags10-sde.sde\sde.sde.s068w013d_Clip'

UNC path: '\\ags10\data\ags10-sde.sde\sde.sde.s068w013d_clip'

Keywords

GDB_TYPE

If CatalogPath points to an ArcGIS geodatabase, then GDB_TYPE is set to GDB_FILE or GDB_ENTERPRISE; otherwise it is set to ' ' (null).

Example

---

Run the following program using ENVI + IDL, and replace the inputFile variable with a real-world dataset.

PRO test_if_gdb

  compile_opt idl2

  ;

  ; First restore all the base save files.

  ;

  envi, /restore_base_save_files

  ;    

  ; Initialize ENVI in the batch mode   

  ; and send all errors and warnings

  ; to the file batch.txt.

  ;

  envi_batch_init, log_file='batch.txt'

  ;  

  ; Open the input file 

  ;

  inputFile = 'C:\Sample.gdb\sample'

  ;

  ; Test if this is a geodatabase

  ;

  is = envi_is_gdb(inputFile, gdb_type=gdb_type)

  print, is

  print, gdb_type

  ;

  ; Exit ENVI

  ;

  envi_batch_exit

END
