==Extract 1D Model Inputs==
'''"-egc control_file.egc"'''<br>
This allows 1D Network (1d_nwk) and/or 1D Cross-Sections to be extracted from a series of grids.<br>
A simple input file similar to the TUFLOW geometry control file is input into the utility. This is nominally given the extension .egc (Estry Geometry Control).<br>

For each line in the cut line layer a cross-section will be extracted and output into .csv file format ready for use in TUFLOW. A number of options can be set for each cut line. Attributes for the cross-section cut line are:

==Extract 1D Nodal Area Tables from Grid==
'''"-na <gis_region_file> <input grid>"'''<br>
Can be used to extract nodal-area (elevation-area) tables from a DEM, and output these in a .csv file format suitable for input into the 1D domain of a TUFLOW model.<br>
The input GIS region file should have the same attributes as the 1d_tab file format produced by TUFLOW. The first attribute ("Source" ) should contain a valid .csv file name.<br>
The out nodal area table extends from the minimum to the maximum elevation in the DEM. A user defined minimum value can be specified using the "Skew" attribute of the GIS region.<br>
Example:<br>
<li><tt>asc_to_asc.exe -na 1d_na_storgae_R.shp DEM_1m.flt</tt><br>
