In GeoSTORM software, the Recompute Routing Reach Properties command allows the user to recompute routing reach properties such as lengths and slopes based upon connected junctions.
Follow the steps below to use the Recompute Routing Reach Properties command:
- From the Input ribbon menu, click the Routing Reaches dropdown menu and select the Recompute Routing Reach Properties command.
- The Recompute Routing Reach Properties dialog box will be displayed as shown below.
The following sections describe how to use the Recompute Routing Reach Properties command and interact with the above dialog box.
Selecting Routing Reaches
The Select Routing Reaches section allows the user to select routing reaches for which properties such as length and slope are to be recomputed. This section includes a table that lists all the routing reaches contained within the current scenario of the project along with their lengths and slopes.
The user can select routing reaches using any of the following methods for recomputing properties:
- By pressing and holding down the [Ctrl] key while selecting the routing reaches directly from the Map View. Immediately after selecting the routing reaches, open the Recompute Reach Properties dialog box, and the selected routing reaches will be shown as selected/checked within the Select Routing Reaches section.
- By checking the checkboxes corresponding to each routing reach in the Select Routing Reaches section.
- By clicking the [Pick] button, the Recompute Routing Reach Properties dialog box will temporarily disappear, and a prompt will be displayed on the status bar instructing the user to select the routing reaches from the Map View. After selecting routing reaches, pressing the [Enter] key or right-clicking and choosing Done from the displayed context menu redisplays the Recompute Routing Reach Properties dialog box.
After selecting routing reaches, the total number of selected routing reaches will be displayed in the Total selected read-only field as shown below.
Routing Reach Properties
This section is used to define the elevation data source and other parameters to be used for recomputing the properties (Length and Slope) for the selected routing reaches.
Terrain Elevation Source
Depending upon the terrain elevation source type selected, the content of the Routing Reach Properties section changes to specify additional elevation data information.
The Terrain elevation source dropdown combo box supports the following surface types:
- CAD Drawing
- Elevation Grid
- GIS Contours
- LandXML Data
- Terrain Surface
- TIN surface
CAD Drawing
If the user selects CAD Drawing as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following options are displayed when the CAD Drawing is selected as the terrain elevation source:
- CAD drawing layer
This dropdown combo box allows the user to select the CAD drawing layer available in the project.
- Drawing layers
Clicking the [Define] button adjacent to the Drawing layers entry displays the CAD Drawing Layers dialog box, allowing the user to define the properties of the drawing layers.
Elevation Grid
If the user selects Elevation Grid as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following option is displayed when the Elevation Grid is selected as the terrain elevation source:
- Elevation grid layer
This dropdown combo box allows the user to select the elevation grid layer available in the project.
GIS Contour
If the user selects GIS Contours as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following options are displayed when the GIS Contours is selected as the terrain elevation source:
- GIS polyline layer
This dropdown combo box allows the user to select the GIS polyline layer type.
- Elevation attribute
This dropdown combo box allows the user to select the elevation attribute type.
LandXML Data
If the user selects LandXML Data as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following options are displayed when the LandXML Data is selected as the terrain elevation source:
- TIN surface layer
This dropdown combo box allows the user to select the TIN surface layer type.
- TIN surface
This dropdown combo box allows the user to select the TIN surface type.
Terrain Surface
If the user selects Terrain Surface as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following option is displayed when the Terrain Surface is selected as the terrain elevation source:
- TIN surface layer
This dropdown combo box allows the user to select the TIN surface layer type.
TIN Surface
If the user selects TIN Surface as the terrain elevation source, the content of the Routing Reach Properties section changes as shown below.
The following options are displayed when the TIN Surface is selected as the terrain elevation source:
- TIN surface layer
This dropdown combo box allows the user to select the TIN surface layer type.
- TIN surface
This dropdown combo box allows the user to select the TIN surface type.
After selecting the terrain elevation source, the user can check the checkbox of the following properties to be recomputed for the selected routing reaches.
- Reach length
This checkbox option is used to recompute the length of the selected routing reaches.
- Reach slope
This checkbox option is used to recompute the slope of the selected routing reaches.
Computing Routing Reach Properties
Once data have been defined in the Recompute Routing Reach Properties dialog box, click the [Compute] button and the software will recompute the properties of the selected routing reaches.
