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.
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.
- Go to ArcToolBox > Data Management Tools > Projections and Transformations > Feature > Batch Project.
- 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
