Adding linear events using route and measure—ArcGIS Pipeline Referencing Server

适用于 Location Referencing 许可。

Route and Measure method

Characteristics of a route such as operating pressure and DOT class can be represented as a linear event with starting and ending measure information along the route. The Line Events tool provides an interface to add linear events into the geodatabase. You can also use referent offset data to add events to a route. The referent offset data is translated to routes and measures for storage.

In this method, the event's from measure and to measure are located on the basis of the measure values from the selected route. As shown in the example below, the from and to measures of the route are 0 and 10, respectively. An event with from and to measures of 2 and 8 can be located on the route. The route and measure method is always the first option (in the form of the network's name) in the Method drop-down list.

Locating event's measure using route's measure

打开 ArcGIS Event Editor 并在出现提示时登录到您的 ArcGIS 组织。
单击编辑选项卡。
In the Edit Events group, click the Line Events button .
The Add Linear Events dialog box appears.
注：
The selections in steps 3, 5, and 8 can be configured in advance when configuring, creating, or editing the default settings for attribute sets. For more information about configuring, creating, and editing default settings for attribute sets, see Producing attribute sets and Configuring attribute sets.
单击网络下拉箭头并选择将用作源线性参考方法 (LRM) 的网络，用于定义新线性事件的输入测量值。
该网络是一个 LRS 网络，作为图层发布在 Event Editor 中。可以指定 LRS 网络用作定义新线性事件测量开始和结束的 LRM。 Event Editor 也接受网络或 LRM 中的测量值，而不是与线性事件图层相关联的测量值。
新事件将与来自 LRS 网络的路径（路径 ID）相关联，事件位置与该路径相交。
使用以下选项之一选择事件所在的线要素的名称：
- 单击下拉箭头，在线名称文本框中选择线名称。
- 单击在地图上选择线工具，然后从地图中选择线。
提示：
如果所选线不在地图的活动视图中，请单击在地图上缩放至线范围或线起点或终点的中心按钮以刷新地图显示以放大所选线的整个范围。
该线以浅蓝色突出显示。末尾的箭头表示线的校准方向。
In the From section, click the Method drop-down arrow and choose the network.
from the Route Name drop-down list, choose the route where the event's from measure value will be located.
- Type the route's name.
- Use the Select a Route on the Map tool to choose the route on the map.
Only routes that are part of the chosen line can be selected.
Provide the intended start location for the new linear event along the route using any of the following options:
- Type the value in the Measure text box.
- Use the Select from Measure on the Map tool to choose the from measure value along the route on the map.
- Use the Measure drop-down arrow to choose either Use the Route Start or Use the Route End as the from measure value for the event.
If you type the from measure value, you can choose the unit for that value using the drop-down arrow. The from measure value is converted to LRS units before saving the newly added events. For example, the LRS is in miles and you typed 528 feet as the from measure value. The newly added events will have a from measure value of 0.1 miles, because 528 feet equals 0.1 miles.
A green plus symbol appears at the selected location on the map.
For the to measure value, repeat steps 6 through 8 in the to section.
A red cross symbol appears at the selected location on the map.
按如下步骤选择事件的开始日期：
- 在开始日期文本框中键入开始日期。
- 单击开始日期下拉菜单，然后选择开始日期。
开始日期默认为今天的日期，也可以使用日期选择器选择不同的日期。
按如下步骤选择事件的结束日期：
- 在结束日期文本框中键入结束日期。
- 单击结束日期下拉菜单，然后选择结束日期。
结束日期是可选的，如果未提供，则事件在现在和将来都仍然有效。
从以下数据验证选项中进行选择，以防止在表征具有线性事件的路径时出现错误输入：
- 停用重叠 - 系统调整现有事件的测量值以及开始和结束日期，以使新事件不会出现时间和度量值重叠。
- 合并重合事件 - 当新事件的所有属性值与现有事件完全相同时，如果新事件在测量值方面与现有事件相邻或重叠，则将新事件合并到现有事件中，而且测量范围将相应扩大。
- 防止测量不在路径上 - 此数据验证选项可确保开始和结束测量的输入测量值落在所选路径上测量值的最小和最大范围内。
单击下一步。
显示事件属性集的选项卡出现。
注：
您可以使用复选框为属性集中的特定事件添加数据。未选中的事件不会添加任何记录。
在属性集定义的表中提供新事件的属性信息。
可以使用复制属性值工具从另一条路径复制事件属性。单击该工具并单击地图上的路径以复制事件属性。
Event Editor 使用默认属性集，位于编辑选项卡上。可以修改属性集以创建自定义属性集或使用管理员配置的属性集。
Use the following options to access more information on the attribute set:
- 选中显示网络名称复选框以显示与所选事件图层关联的 LRS 网络。
- 由属性集定义的表中的属性列表可以来自多个事件图层。如果要识别每个属性的源事件图层，请选中显示图层名称复选框。
- Checking the Go to the next measure upon save check box results in prepopulating the from measure value using the to measure value of the present section to continue the event creation process.
单击保存。
新线性事件已创建并出现在地图中。新添加的线事件保存后，将在右下角显示一条确认消息。
