Problem: Batch Project script tool does not transform datums

Description

The Batch Project script in ArcToolbox > Data Management Tools > Projections and Transformations > Feature fails to transform data from one Geographic Coordinate System (datum) to another.

Cause

The name of the required Geographic Transformation is not given, and there is no drop-down menu provided from which a selection may be made.

Solution or Workaround

'Transformation (optional)' found in the Batch Project dialog box, provides a space in which to enter the datum transformation name. The transformation name must be typed into the box to apply the datum transformation during the Batch Project process.

  1. Go to ArcToolBox > Data Management Tools > Projections and Transformations > Feature > Batch Project.
  2. In the space provided below 'Transformation (optional)', type the name of the datum transformation. Underscores must be included, but it is not case-sensitive.

    For example: To transform between NAD 1927 and NAD 1983 in the 48 contiguous states, type the following string into the 'Transformation (optional)' space in the dialog box: nad_1927_to_nad_1983_nadcon
