XPSWMM reads its 2D DTM data in one of two ways:
* The DTM data can be directly specified in the '2D Model Settings', or
Line 25:
</ol>
==
If 'Use DTM' was selected, XPSWMM pre-processes its Digital Terrain Model (DTM) into a binary XPTIN elevation dataset for inclusion in the TUFLOW model. XPTIN is a propriety format that can't readily be used in GIS software. For this reason, the following section outlines how to obtain a DTM dataset in a GIS friendly form. <br>
Line 33:
XPSWMM provides two options for preprocessing the DTM to be used in the TUFLOW model, both options are outlined below. As 'Option 1' is straightforward and 'Option 2' is more involved, 'Option 2' is demonstrated in the video below.
<br>
<ol>
<li> Locate the original 'Grid' file (.asc or .flt/.hdr format). Save it to the folder where XPSWMM writes the .tcf during its simulation preprocessing. By default, this is the '''2D\Data''' folder. <br>

<li> In the XPSWMM Layers panel, under 'Topography', right click on '''DTM''' and select 'Export DTM Data'.
