The following sections explain how 2D data can be exported from XPSWMM and/or reconfigured into a format that is more standard of a TUFLOW model. The conversion has been summarized into three steps:
<ol>

== Digital Terrain Model (DTM) Data ==
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 28 ⟶ 29:
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>
:'''Note:''' If 'Use DTM' was selected, follow the steps below. Otherwise, <u>do not</u> complete these steps; continue to the <u>[[
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.
