# How to use Global Coordinates

To process with control points measured using the global coordinate system:

1. Add one commented line in the control point CSV file. An example is shown in the first line below:

```plaintext
#, CRS, EPSG:2169,
id, x, y, z # this line is optional
ABC, 1000000.0, 2000000.0, 3000000.0
DEF, 4000000.0, 5000000.0, 6000000.0
```

1. SiteMaker can process the data without error, and later one can directly import the processed data into IVION with the same coordinate system selected.

> **Note**: when using this method, you'll still receive the following warning in the processing log:
> 
> “Warning: At least one control point has a coordinate value outside of the range of a local metric coordinate system: |val| > 20000.0”
> 
> This can be ignored as long as the processing is not interrupted by an error message.
