40005: Layer's dataset is using an unknown coordinate system

A coordinate system is required for your layer's dataset when creating a package.

Solutions

More information

Coordinate systems provide a mechanism for describing geographic data on a 2D and 3D surface. It is considered a best practice to have a coordinate system defined for your map or layer so that it can be correctly represented and integrated with other layers of a map.

Changing the data frame's coordinate system

  1. Right-click the data frame for which you want to determine the coordinate system.
  2. Click Properties.
  3. Click the Coordinate System tab. The details of the current data frame coordinate system are shown in the dialog box.
  4. For more information, see Specifying a coordinate system.

Changing the coordinate system of a map layer

You must define the coordinate system of the data source used for the map layer. See the Define Projection geoprocessing tool for more information.
