TUFLOW Message 0307
TUFLOW Message
WARNING 0307 - No MI Projection or mif header file ",a," found. Non-Earth Coordinates will be used.
Alternate Message
No GIS Projection specified. No output .prj file will be created.
Message Type
WARNING
Description
The geographic projection for GIS input and output data in MID/MIF format has not been defined using the command MI Projection == . When this command is omitted, TUFLOW searches for a file 'Header.mif' in each folder it opens a MID/MIF GIS file and extracts the projection from this file. If no 'Header.mif' file is found, non-earth coordinates are assumed.
Suggestions
Create a projection file by following the instructions outlined on this Wiki page.The created layer then needs to be referenced using the following .tcf command:
MI Projection == ..\model\mi\Model_Projection.mif
Alternatively, a projection line may be extracted from a MIF file by following these steps:
- In a GIS, create or open a layer in the Cartesian projection to be used for the model.
- Export the layer in MIF/MID format.
- Open the .mif file in a text editor, copy the whole line starting with “CoordSys” (usually the 4th or 5th line).
- Paste the text after the command paste after MI Projection == in the .tcf file.
MI Projection == CoordSys Earth Projection 8, 13, "m", 153, 0, 0.9996, 500000, 10000000 Bounds (-7745874.38492, 1999.40969607) (8745874.38492, 19998000.5903)
If a model has a mixture of .mif and .shp files as input, then both the tcf commands MI Projection == and SHP Projection == should be specified.
