ArcMAp smooths (interrupts) line elements, and arcmap line elements interrupt

I. Tool introduction-ArcMAp10.1 provides tools for summarizing and Smoothing Line/Plane elements.

Summary Tools and smoothing tools are as follows: (you must enable the editing status before you can change the attribute of the element.) Select a element (such as a subway line) (the left arrow is incorrect, correct the following: Mark ArcCatelog as a directory; List of content on the left of ArcCatelog; List of marked content is actually a search; others remain unchanged)

 

II:Summary/smoothness:

 

Iii. General operations and smooth operations

(1) Principle: the basic principle of the general operation: An algorithm is used to extract a part of the original element from the point set to form a subset of the origin set.

(2) Basic Principle of the smooth operation: the smooth operation is actually completed in two steps. First, the original vertex set is summarized, and then the subset obtained in the previous step is Bessel) interpolation to get smooth results. See the following smoothing principle:

(3) Summary of elements:

Click Edit tool, select the elements to be operated, and click summarize tool.

In the displayed dialog box, enter the maximum allowed offset (the default unit is the same as that of the current map, and the unit cannot be entered after the value ).This value limits the maximum offset between the processed result graph and the source image.

Click "OK.(I chose 0.000009)

(4) smooth element operation steps:

Click Edit tool, select the elements to be operated, and click summarize tool.

In the displayed dialog box, enter the maximum allowed offset (the default unit is the same as that of the current map, and the unit cannot be entered after the value). This value plays a transitional role in the processing, that is, it plays a role in generalization of the original vertex set.

Click "OK.(I chose 0.000009)

4. Interrupt the line (partially reproduced from the arcgis official website)

(1) manual disconnection
Split tool 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 Given length and percentage
Split in the Editor toolbar drop-down menu breaks the line at a given length or percentage of 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.

Create a DOT/Line Element In arcmap

You cannot create layers In arcmap. You must first create a new vertex, line, and surface layer in arccatalog, and then load it to arcmap. After editing, you can add some, line, and surface elements to the corresponding layer.
 
How to scatter elements In arcmap

There is a more Editing Tools-"Advanced Editing under the Editor drop-down menu, and there is a bomb icon in it, that is, Explode Multi Part Feature
Select the object to be dispersed and click this button.
