XPSWMM Conversion DTM Archive: Difference between revisions

XPSWMM reads its 2D DTM data in one of two ways:

* The DTM data can be directly specified in the '2D Model Settings', or

</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 options outline how to obtain a DTM dataset in a GIS friendly form. <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'.
