Latitude == [ {0} | ]

(Optional)

Sets the latitude used for calculating the Coriolos term in the shallow water equations. Negative value indicates south of the equator. A zero value disables the Coriolos term.

MI Projection == [ <.mif file> |
]

(Optional but recommended)

Sets the geographic projection for all GIS input and output. If this command is omitted, TUFLOW searches for a file “Header.mif” in each folder it opens GIS files, and extracts the projection from this file. The “Header.mif” file is any GIS layer in the correct projection exported in MIF/MID format. If no “Header.mif” file is found, non-earth coordinates are assumed.

Note: The projection must be Cartesian and in meters.

As of Build 2003-12-AD, a mif file can be specified and the projection line is extracted from this file, and is the referred approach than that described below.

To enter a projection line from a mif file, follow these steps:



  1. In a GIS, create or open a layer in the Cartesian projection to be used for the model. For non-geographic models (eg. a test model), use the Non-Earth (meters) projection.

  2. Export the layer in MIF/MID format.

  3. Open the .mif file in a text editor, copy the whole line starting with “CoordSys” (usually the 4th or 5th line) and paste after “MI Projection ==” in the .tcf file.

Example:

MI Projection == CoordSys Earth Projection 8, 13, "m", 153, 0, 0.9996, 500000, 10000000 Bounds (-7745874.38492, 1999.40969607) (8745874.38492, 19998000.5903)



Note: All GIS layers read by TUFLOW MUST USE this projection. The projection must be a Cartesian based projection, not a spherical projection such as Latitude/Longitude.

Snap Tolerance == [ {0.001} | ]

(Optional)

Sets the search distance in metres for detecting whether two GIS objects are connected (snapped). Introduced in Build 2005-05-AN.
