ERROR 10383 - Could not read projection line in .prj file.

Description

TUFLOW FV reads the coordinate system definition from the .prj file that accompanies a shapefile. This error is raised when the projection string in the .prj file cannot be parsed. The spatial reference of the shapefile cannot be determined.

Suggestions

Check the .prj file associated with the failing shapefile. It should contain a valid Well-Known Text (WKT) coordinate system definition. Common causes include a corrupt or empty .prj file, or a non-standard projection format not recognised by TUFLOW FV.

Check the projection string of the offending layer matches the TUFLOW FV GIS template layers generated by Write Empty GIS Files during model initialisation. See the model initialisation section of the TUFLOW FV User Manaul for further details on this process. If the projection string does not match, import a new empty layer and copy over the file content into the new empty layer.
