001003 : Datum conflict between input and output.

Description

The output data's geographic coordinate system (datum) is different from one of the input(s). The coordinate system of an output is determined by the coordinate system of the first input or by the output coordinate system environment, if set. This warning can occur in the following cases:

• Feature data is being written to feature dataset that has a different datum from the input.
• The output coordinate system environment is set.
• An overlay operation is used on input feature classes with different datum.

Solution

This is a warning; no change is necessary. If the warning is unexpected, check the current setting of the output coordinate system environment. The default setting is set to Same as Input.
