Define projection
Function Description: Overwrite the coordinate system information (map projection and datum) stored with the raster data.
Data Description
- All geographic data have a coordinate system used for displaying, measuring, and transforming the data. If the coordinate system of a dataset is unknown or incorrect, you can use this tool to specify the correct coordinate system.
- This tool only updates the existing coordinate system information; it does not modify any data. To transform data to another coordinate system, use the Project tool.
Steps
- Locate the Define Projection tool under Raster Tools in the toolbox, and double-click to open the tool's window.
