Selecting events by proximity

You can use the proximity selection tools available in the Event Editor to select events on the map on the basis of their nearness to a given feature. The selection tools are:

Proximity Option	Function
Along route path	Selects events intersecting a route on either side of a point selected on the route.
Buffer from location	Selects events intersecting a buffer from a point location selected on the map.
Buffer from route	Selects events intersecting a buffer created on a route segment.

Selecting events along a route path

You can select events using their proximity from a particular point along a route. For example, if there is an error in data at a point on the route and you want to find the events along the route that might be affected by that erroneous point.

1. 打开 Event Editor，根据提示登录 Enterprise 门户或 ArcGIS Online。
2. 单击编辑选项卡。
3. Choose the event layer from which to select events.

   You can browse the list of layers by keystroke. For example, press the S key in the drop-down menu to jump to the first layer in your list that begins with the letter s.

4. In the Selection group, click Select > Select by Proximity.

   

   The Select by Proximity widget appears.

   

5. Optionally, click the Type drop-down arrow and choose Along route path.
6. Click the Network drop-down arrow and choose the network associated with the event.
7. Type a route ID in the RouteId text box.

   提示：

   也可以单击在选择地图上的路径 以在地图上选择路径。

8. Type a measure value from which the proximity of the events will be calculated in the Measure text box.

   提示：

   也可以单击选择地图上的起始测量值 以在地图上选择路径位置。

9. Type a proximity distance in the Distance text box.

   All the events within this distance on either side of the point that intersect the route will be selected. The proximity will be calculated based on the measure values along the route.

10. Click the units drop-down arrow and choose the units for the proximity distance.
11. Click Select.

All the events within the proximity distance, for example 1.2 miles, on either side of the point along the route will be selected. The results will be displayed in the form of a table.

Once the event records are selected, you can browse and edit them using the results grid.

注：

You cannot edit the selected routes.

Selecting events using a buffer from a location

You can select events using their proximity from a point location on the map.

For example, you can check whether all the roads within a particular buffer distance from a school are designated to have a speed limit less than 25 miles per hour.

1. 打开 Event Editor，根据提示登录 Enterprise 门户或 ArcGIS Online。
2. 单击编辑选项卡。
3. Choose the event layer from which to select events.
4. In the Selection group, click Select > Select by Proximity.

   

   The Select by Proximity widget appears.

5. Click the Type drop-down arrow and choose Buffer from location.

   

6. Type the geographic latitude and longitude values of a point location on the map in the Location text box.

   The proximity will be calculated from this location.

   提示：

   也可以单击在地图上选择位置 以在地图上选择位置。

7. Type a buffer distance in the Distance text box.

   All the events that intersect this buffer distance will be selected.

8. Click the units drop-down arrow and choose the buffer units.
9. Click Select.

All the events that intersect the buffer zone, for example 1 mile from the point location, will be selected. The results will be displayed in the form of a table.

Once the event records are selected, you can browse and edit them using the results grid.

注：

You cannot edit the selected routes.

Selecting events using buffer from a route segment

You can select events using their proximity from a road segment on the map.

1. 打开 Event Editor，根据提示登录 Enterprise 门户或 ArcGIS Online。
2. Click the Edit tab.
3. Choose the event layer from which to select events.
4. In the Selection group, click Select > Select by Proximity.

   

   The Select by Proximity widget appears.

5. Click the Type drop-down arrow and choose Buffer from route.

   

6. Click the Network drop-down arrow and choose the network associated with the event.
7. Type a route ID in the RouteId text box.

   提示：

   也可以单击在选择地图上的路径 以在地图上选择路径。

8. Type the start measure value of the route segment in the From Measure text box.

   提示：

   You can also click the Select From Measure on the Map button to choose the route location on the map or click the drop-down arrow to use the route's start measure.

   The start measure value is represented by a green cross on the map.

9. Optionally, type the end measure value of the route segment in the To Measure text box.

   提示：

   You can also click the Select From Measure on the Map button to select the route location on the map or click the drop-down arrow to use the route's end measure.

   The end measure value is represented by a red x on the map.

If you do not enter the From and To measures, the complete route will be regarded as a road segment to calculate the proximity.

10. Type a buffer distance in the Distance text box.

    All the events that intersect this buffer distance from the route segment will be selected.

11. Click the units drop-down arrow and choose the buffer units.
12. Click Select.

All the events that intersect the buffer zone, for example 1 mile from the road segment, will be selected. The results will be displayed in the form of a table.

Once the event records are selected, you can browse and edit them using the results grid.
