How To: Define the coordinate system of files in a batch process


Instructions provided describe the steps for using the Batch Define Coordinate System script in ArcToolbox to define the coordinate system of multiple datasets simultaneously.

In versions of ArcGIS including and later than version 9.2, all Geoprocessing tools support batch processing by right-clicking the tool and selecting Batch.


The following steps can be executed in both ArcMap and ArcCatalog.

If the Samples toolbox is already listed in ArcToolbox, skip steps 2-4.

  1. Start ArcToolbox.
  2. Right-click ArcToolbox and select Add Toolbox.
  3. Browse to C:\Program Files\ArcGIS\ArcToolbox\Toolboxes and select Samples.tbx.
  4. Click Open. The new Samples toolbox displays.
  5. Expand the Samples Toolbox > Data Management Tools > Projections and double-click the Batch Define Coordinate System script.
  6. Add the datasets to be defined.
  7. Specify the coordinate system.
  8. Click OK.
