Line 182:
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>
<br>
Two input GIS layers can be used, these are the branch lines and cut lines. The branch line is split into the 1d_nwk layer, a new 1D channel is created for each section. The GIS attributes of these are defined in the sections below.

! Command
! width=90% | Description
|-
|Read GIS Branch|| Reads the branch lines, these are described above.
|-
|Read GIS XS|| Reads the cross-section cut lines, these are described above.
|-
|Set XS dx|| Sets the default distance across section to extract elevations and materials data. This can be specified on the cut lines as detailed above.
|-
|Set XS Z|| Sets the elevation for all points in all cross-sections.
|-
|Set XS Mat|| Sets the material ID for all points in all cross-sections.
|-
|Read Grid Z|| Read elevations from DEM and assign this to all cross-section extraction points that fall within active DEM pixels.
|-
|Read Grid Mat|| Read material IDs from raster grid and assign this to all cross-section extraction points that fall within active DEM pixels. This should be an integer grid.
