Line 19: = XPSWMM DTM Preprocessing = If 'Use DTM' was selected, XPSWMM ~~pre-processes~~preprocesses its Digital Terrain Model (DTM) into a binary XPTIN elevation dataset for inclusion in the TUFLOW model. XPTIN is a binary 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> 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. Line 26: == Option 1 (recommended) - Use Original Source Elevation Data Imported to XPSWMM == <ol> <li> If you personally built the XPSWMM model, you should know ~~when~~where the original source DTM dataset can be found. Locate the original 'Grid' file (.asc or .flt/.hdr format). Save it to the folder where XPSWMM writes the .tcf during its simulation preprocessing. <br> By default, this is the '''2D\Data''' folder. If this folder does not exist, either: :* The XPSWMM model has not run, so the TUFLOW control files have not been created by XPSWMM. Run the XPSWMM model (go to Analyze > Solve... in top dropdown menu options).
