Coastal zone for a predetermined distance, and as the value for the buffer segment and the calculated range of the buffer

Demand: 10000km need to interrupt line the coastal zone in the layer every coastal zone.

When ArcGIS vector processing data, we often encounter the problem of broken lines, such as the need to interrupt the line somewhere on the specified line, or line segments need to be online to play at the intersection when a new network dataset, and so on. The desktop version of the tool will now be interrupted line I encountered summarized as follows:

Method a: the tools used ArcToolBox Editing Tools -Densify online 10000km added every other node (Vertex).


Before and after the operation

Then call ArcToolBox tools in Data Manager Tools-Features-Split Line At Vertices

According to break a line node (Vertices).

The results are shown:

A hand break line

split tool Editor toolbar.

When you use this tool, select the line to be interrupted, if required precise interrupted, you can then editor / capture settings at snapping, then click on the line, you can break the line in place of a mouse click, the properties of the original line are copied to all each of the new line

Second, given the length of the interrupted line

1, the percentage of a given length or the length of the interrupted line

Editor toolbar drop-down menu in split

Using this tool can be selected line feature broken into two parts. Counting from the start point or end point of the line break line. Using a given value of length, long wire or a percentage value M break a line into several parts. First of all elements of the value of property to the new production line.

Under state must edit, and select the line layer to be operated, editing drop-down list split is available.

2. The establishment of buffer zones

3. Calculate the average of the lower portion of the buffer

Generating the average value of the ten buffers

export excel spreadsheet format dBase table.

3.1 second try

4. given distance interrupted line

Editor toolbar drop-down menu in the divide

When you use this tool, select the line to break, divide click Tools, unites enter values ​​in the place point separated by every -----, be determined

Note: split and divide the difference: just split our request interrupt line, the original line feature has been removed; and divide
is to break the lines to generate new elements, depending on the point layer or line chart target set layer, retained the original line elements.

Third, the line of intersection of the line break

1, line intersection in the Advanced Editing toolbar

Using this tool intersects the line segment can be interrupted.
At the same time there is a case that the fancy not connected to link portion intersects

At this time, when using the tool, first click the first element intersects a line, and then click the second intersecting line elements, press O,

The following dialog box appears

When the first option is selected, two lines will not intersect at a point connected to the extension of health, the break point;

When you select the second option, Nobu section generates a new element

2, interrupted lines all intersect in place to make the network dataset

Planarize lines in the topology toolbar
to select all the elements, just click planarize lines, be determined

Fourth, according to other requirements interrupted line

1, broken lines at the node line
