=== Define Elevations ===
In the previous section, the extent and dimensions of the 2D domain were defined. We now need to assign elevations at each 2D cell centre, mid-side and corner. These points are known as Zpts.<br>
Knowledge of 2D domain geometry is fundamental to understanding how TUFLOW works. A brief description on the computational function of each of the Zpts in a TUFLOW cell is given in the <u>[[Zpt_Description | Zpt Description]]</u> page. It is also highly recommended to read the ''2D Model domain Schematisation'' Section of the <u>[
<br>
There are two methods to assign the elevations to the Zpts. The first is to directly input the elevation model into TUFLOW as either a TIN or gridded DEM dataset. TUFLOW will assign the elevations from the elevation dataset to Zpts within the DEM / TIN. This offers the following benefits:<br>
