Output coordinate system
Release 9.2 Last modified September 4, 2007	Print all topics in : "General settings"

Specify the coordinate system that will be used for processing and set to the output geodataset. The coordinate system (geographic or projected) defines the location of the spatial data on the earth.

If the geoprocessing tool has an input feature class, and the coordinate system environment is not set, the the coordinate system of the input* will be used as the processing and set as the output feature class' coordinate system. To override this, set the "Coordinate System environment" to the desired coordinate system.

* For tools which have multiple inputs (intersect for example) the coordinate of the first feature class in the list will be used.

Usage tips

• When the coordinate system environment is different than the input feature class' coordinate system, the input features are projected to the output coordinate system during tool execution. This projecting of the features will not affect the input feature class. Keep in mind that a projection can only be done between two known coordinate systems. So if either the input or output dataset's coordinate system is unknown, no projection occurs. Then the input feature's coordinates are assumed to be in the same coordinate system as the processing and output coordinate system.
  

• The keyword used at the command line or in scripts for this environment setting is OutputCoordinateSystem.
  
• If not explicitly set and the output does not reside inside a feature dataset, the coordinate system of the first input will be used.

Command line syntax

An overview of the command line window

OutputCoordinateSystem <outputCoordinateSystem>

Parameters	Explanation	Datatype
<outputCoordinateSystem>	Specifies the output features coordinate system. If not explicitly set and the output does not reside inside a feature dataset, the spatial reference of the first input will be used. Same As Input—If input features have a coordinate system, then the output features will have the same coordinate system. This is the default. As specified below—Choose a new coordinate system for output features. You may enter a coordinate system name or use the Spatial Reference Properties dialog box.	Coordiante System

Parameters	Explanation	Datatype
outputCoordinateSystem (Required)	Specifies the output features coordinate system. If not explicitly set and the output does not reside inside a feature dataset, the spatial reference of the first input will be used. Same As Input—If input features have a coordinate system, then the output features will have the same coordinate system. This is the default.
