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:

#, 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

2. 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.
