Line 1: =Introduction= The native non-Graphical User Interface (GUI) form of TUFLOW uses Geographic Information System (GIS) files for its spatial inputs. TUFLOW requires precise GIS file formats associated with specific TUFLOW commands. The required fields for each input type are listed in the <u>[https://downloads.tuflow.com/_archive/TUFLOW/Releases/2018-03/TUFLOW%20Manual.2018-03.pdf TUFLOW Manual]</u>. For example, the '''~~1d_zsh_empty~~2d_zsh_empty''' file associated with the <font color="blue"><tt>Read GIS Z Shape</tt></font> <font color="red"><tt>==</tt></font> command requires the following data fields and types in the order shown below:<br> ~~[[File: TUFLOW_Empty_File_ZShape_Format.PNG]]<br>~~ <center>[[File:2d zsh fields.png]]<br></center> Because of this file format requirement, the first task in any modelling project is to write template (empty) GIS files (as demonstrated in <u>[[Tutorial_M01#Project_Initialisation\|Tutorial Module 1]]</u>).<br> This page of the TUFLOW Wiki provides a reference list of the template (empty) GIS files, the associated TUFLOW command and a basic description of their function.<br>▼ <br> ▲Because of this file format requirement, the first task in any modelling project is to write template (empty) GIS files in the specific model projection system (as demonstrated in <u>[[Tutorial_M01#Project_Initialisation\|Tutorial Module 1]]</u>).<br> ~~This page of the TUFLOW Wiki provides a reference list of the template (empty) GIS files, the associated TUFLOW command and a basic description of their function.<br>~~ This page of the TUFLOW Wiki provides a reference list of the template (empty) GIS files, the associated TUFLOW command and a basic description of their function.<br> Note: when using the shapefile format TUFLOW creates a dummy entry when creating empty files. Importing an empty layer into QGIS using the <u>[[QGIS_TUFLOW_Import_Empty \| Import Empty]]</u> tool, will remove this dummy entry. Opening a template empty file directly in QGIS (without using the <u>[[QGIS_TUFLOW_Import_Empty \| Import Empty]]</u> tool), the dummy entry will remain in the layer and garbled text shown in the attribute fields. ==TUFLOW Control file (TCF)==
