BATCH NODE (BatNod)

Type: Batch application

Nodes lines

Detailed Description

Nodes lines in VrOne workspaces. A node is the intersection of two lines. Options include:

Ability to node line only, which places a common point on each line at the intersection.
Ability to node and break lines at intersections.
Support for Z Rules

Available Key-ins

Parameters for Batch Node

Pass

This batch application allows up to twenty passes on the workspace(s). For example, this would allow one session to node driveways to buildings, driveways to road edges, sidewalks to buildings and fences to buildings.

Workspaces to consider

Defines the workspaces to consider when running batch node.

Workspaces mode

Can be set to “Node Between Workspaces” or “Do Not Node Between Workspaces”. When working on multiple workspaces, this determines whether or not lines that cross between workspaces are considered for noding.

Pass Name

User defined pass name for information only.

Target Layers

Layers containing lines to be nodded with source layers. These lines are considered line 1 for the Z rule. A number line may be used to define the layers.

Source Layers

Layers containing lines to be nodded with source layers. These lines are considered line 2 for the Z rule. A number line may be used to define the layers.

Break Mode

Specifies the break mode when two lines are nodded. Options are “Node only” in which a node point is placed on each line at the intersection and “Break and node” in which the lines are broken at the intersection.

Z Rule

The rule for computing the elevation at the intersection of the two lines. During nodding an elevation for each line is computed at the break point. These elevations are based on the slope of the line segment as determined by the point before and after the break point. The Z Rule determines the action to be taken on these two elevations as follows:

Original elevations – The elevations of the break points is not modified

Mean node elevations – The elevations are averaged and stored for both node points.

Elevation from line 1 – The elevation from the node point on line 1 is used on both lines.

Elevation from line 2 – The elevation from the node point on line 2 is used on both lines.

Search Distance

Defines the distance to search from the target lines for source lines.

This parameter is used to find undershoots and is set in ground units.

NOTE: The Search Distance should be kept as small as possible. Unexpected results may occur if this parameter is unreasonable.

Short Distance

Any clipped line segment that is shorter than this distance will be deleted.

If the clipped line segment is longer than this distance, it will be left in the file.

This parameter is used to delete overshoots and is set in ground units.

NOTE: The Short Distance should be kept as small as possible. Unexpected results may occur if this parameter is unreasonable.

NOTE: The Short Distance should always be smaller than the Search Distance.

Create Drive File?

A line end that is not noded during this process may have its coordinate stored in the Batch Node Drive File. These un-noded points may be visited and corrected by using the VrOne drive file functions.

NOTE: Drive files will only be created when the Break Mode is set to “Break and Node”.

Warning:

Even though Batch Node is un-doable VrOne files should be backed up before use.
