Batch Define Coordinate System

Summary

Records the coordinate system information for the specified input datasets including any associated projection parameters, datum, or spheroid. It creates or modifies the dataset's projection parameters.

Usage

  • This command can be used if the input datasets do not have a projection defined. If either of the input datasets has a projection defined, a warning will be raised but the tool will execute successfully.

  • The input datasets can include feature classes, raster datasets, and layers.

  • The coordinate system information of the input is created or modified by this tool. No separate output feature class will be created.

  • If the input datasets do not have a projection defined, the coordinate system will be listed as Unknown on the dialog box.

  • If either of the input datasets has a coordinate system defined, use the Project tool to modify it.

  • Use the Spatial Reference Properties dialog box to select a coordinate system definition from an existing definition list or dataset, or create a new coordinate system definition.

  • Use the template parameter to select an existing definition from another dataset to create a new coordinate system definition.

  • Either a coordinate system or a template dataset must be specified for the tool to execute.

  • When using this tool in ModelBuilder, the outputs will be two Boolean parameters. One parameter is named Completed and the other is named Error. These parameters are provided to allow chaining in ModelBuilder. Preconditions can be established with other processes. This will allow branching in models. If the tool fails, the model can stop or run another series of processes. If it completes successfully, the model can continue running.

Syntax

[input_datasets,...]

Datasets whose projection is to be defined. The datasets can be feature classes, raster datasets, and layers.

Geodataset
Coordinate_System
(Optional)

Name of the coordinate system to be applied to the input datasets.

Coordinate System
Template_Dataset
(Optional)

Dataset that will be used to select an existing projection definition to be applied to the input datasets.
