CRS Validation

This function is part of the import functionality.

When a file is read during import, Quadri will check if the file has coordinate reference system (CRS) information. Not all file formats have this, some file formats may have CRS information, but do not need to have it. Sometimes the CRS information given is wrong.

During the reading of the file, a pop-up dialog with choices for how to handle CRS might be presented for you:

The file has no CRS information available

• File CRS is the same as in the active Quadri model.

• File CRS is different from the active Quadri model - You cannot import data into the active Quadri model, but view data only.

• Cancel import - If you are not sure about the correct CRS, you may want to check this first before you do the import.

The file contains CRS information - is it correct?

Select whether to continue with the original CRS info from the file(s) - or to set another CRS.

• CRS is correct - Continue.

• CRS is wrong - Set a different CRS. A new dialog for selecting the CRS will then appear.

• Cancel import - If you are not sure about the correct CRS, you may want to check this first before you do the import.

Transformation is necessary to import the files

The file has a CRS that is different from the active Quadri model. To import this file a coordinate transformation has to be performed.

• Use available transformation - Transformation will be performed when you click Finish, or when you preview with the conversion rule selected.

• Cancel import - If you are not sure about the correct CRS, you may want to check this first before you do the import.

Transformation is not supported between the CRSs

• View data only - Importing the file to the Quadri model is not possible.

• Cancel import - If you are not sure about the correct CRS, you may want to check this first before you do the import.
