Line interruption problem)

When processing data, we often encounter line interruptions. For example, we need to specify a line to interrupt online, or set a line at the online intersection when creating a network data set. The online interrupt tools I encountered in the desktop version are summarized as follows:

I. manual disconnection

Splittool in the editor toolbar.

When using this tool, select the line to be interrupted. If you need to precisely interrupt, you can set capture under Editor/snapping and click the line to interrupt the line where you click the mouse, all attributes of the original line are copied to each new line. The effect is as follows:

 

2. Interrupt line with a given length

1. Interrupt the line at a given length or percentage of Length

Split in the drop-down menu of the editor Toolbar

You can use this tool to break the selected line element into two parts. The line is interrupted from the start or end of the line. Use a given length value, percentage of wire length, or m value to break the line into several parts. All attribute values of the first element are copied to the new production line.

For example, the element arrow shows the line direction, so you can specify the starting or ending point of the line to interrupt the line. The starting point of the differential line reading can be achieved using a symbolic tool.

 

2. Interrupt the line at a given distance

Divide in the editor toolbar drop-down menu

When using this tool, select the line to interrupt, click the divide tool, and enter a value in place point separated byevery ----- unites. The effect is as follows:

Note: The difference between Split and divide: Split only interrupts the line according to our requirements, and the original line element has been deleted. divide is a new element for generating broken lines, this depends on whether the point layer set by the target is a line layer, and the source line element is retained.

3. proportion tool under the COGO Toolbar

When using this tool, line elements can be divided into different line segments based on a given distance. This tool is very useful in accurate measurement. Proportion Value = (length/entered length) * feature length

 

3. Interrupt the line at the intersection of the line

1. line intersection under the advanced editing Toolbar

This tool can be used to interrupt the intersection line segments.

At the same time, there is such a situation that the parts that are not connected are connected to each other, such

When using this tool, first click the line element of the first intersection, then click the line element of the second intersection, and press the O key. The following dialog box is displayed:

When the first option is selected, the two non-intersecting lines will be extended to the point and interrupted at the point out;

When the second option is selected, the extended part will generate a new element.

 

2. All cables are broken at the intersection to form a network dataset.

Planarize lines under the topology Toolbar

Select all elements and click planarize lines to confirm.

4. Interrupt the line according to other requirements

1. Line interruptions at online nodes

Data management tools/Features/split line at vertices

 

2. Use the pointonlineoverlayer function in FME to interrupt the line of the online vertex element.

The procedure is as follows:

A. Right-click arctoolbox and select new toolbox.

B. Right-click new toolbox/New/spatial ETL tools.

C. Set the input data source format, data source, and output data format according to spatial ETL tools in sequence.

D. Select the pointonlineoverlayer function and connect to the node as shown in.

E. Click Run translation.
