sdf_to_GIS.exe will output five GIS files and a series of csv files, one for each cross-section.
<u>TUFLOW Input</u>
<ol>
<li> <tt>1d_xs_<sdf_filename>_surf_line<tt>: <br>
<li> <tt>1d_xs_<sdf_filename>_surf_line<tt>: <br> TUFLOW Input - This dataset defines the location of the cross-sections. The file uses a format that is compatible with TUFLOW. The field attributes for "Source", "Type" and "Flags" have been pre-filled.
<li> cross-section csv files: TUFLOW Input - This dataset defines the cross-section properties. Across channel distance, channel elevation and manning's roughness have been pre-filled with the csv datasets.
<li> <sdf_filename>_streams:cross-section Checkcsv File -files: This filedataset defines the centerline of the channel. This centerline data can be split using the cross-section dataproperties. toAcross define thechannel 1Ddistance, channel (1d_nwk)elevation inand amanning's TUFLOWroughness model.have Ifbeen usedpre-filled as a 1d_nwk inputwith the followingcsv fielddatasets. attributes should be used:

<u>Check File</u>
<li> <sdf_filename>_streams: This file defines the centerline of the channel. This centerline data can be split using the cross-section data to define the 1D channel (1d_nwk) in a TUFLOW model. If used as a 1d_nwk input the following field attributes should be used:
<ol>
<li>"Len_or_ANA"= 0 (the length of the line/polyline is used)
<li>"DS_Invert"= -99999 (the bed of the channel cross-section is used)
</ol>
<li> <sdf_filename>_cut_line: Check File – Echo of the cross-section line (non-trimmed)
<li> <sdf_filename>_levee_pts: Check File – Points defining the intersection of the cross-section line with the levee used to trim the cross-section dataset
<li> <sdf_filename>_surf_line: Check File – Point dataset reporting the location of each elevation values within the csv cross-section dataset.
</ol>
