Detect Overlaps For Linear Events

サマリー

Checks routes on the network for overlaps between linear events.

使用法

• The input Event Layer must be one of the linear event tables registered with the input Network Layer.

• The Output Feature Class represents the overlaps between linear events.

• The Output Feature Class contains the following fields: NetworkName, RouteID, TVD (Temporal View Date), EventLayer, FromMeasure and ToMeasure.

構文

DetectOverlapsForLinearEvents_locref (in_network, in_event, out_feature, {in_tvd}, {in_from_measure}, {in_to_measure}, {in_tolerance})

パラメーター	説明	データ タイプ
in_network	The network containing the linear event features to be checked for overlaps.	Feature Layer
in_event	The linear event features to be checked for overlaps.	Feature Layer
out_feature	The output feature class containing lines where there are overlapping events.	Feature Class
in_tvd (オプション)	The temporal view date for the network.	Date
in_from_measure (オプション)	Defines the lower bound of the portion of the route on which overlaps will be detected.	Double
in_to_measure (オプション)	Defines the upper bound of the portion of the route on which overlaps will be detected.	Double
in_tolerance (オプション)	Tolerance, in LRM (Linear Referencing Method) units, used to compare events on routes.	Double

コードのサンプル

DetectOverlapsForLinearEvents example 1 (in-line)

The following Python window script demonstrates how to use the DetectOverlapsForLinearEvents function in immediate mode.

# tool variables
in_network = "MilePoint"
in_event = "Functional_Class"
out_feature = "Overlaps_Output"
in_tvd = "2/28/2014"
in_to_measure = ""
in_from_measure = ""
in_tolerance = ""

# set current workspace
arcpy.env.workspace = "C:/data/Outputs.gdb"

# execute the tool
arcpy.DetectOverlapsForLinearEvents_locref(in_network, in_event, out_feature, in_tvd, in_to_measure, in_from_measure, in_tolerance)

DetectOverlapsForLinearEvents example 2 (stand-alone Python script)

The following Python script demonstrates how to use DetectOverlapsforLinearEvents in a stand-alone Python script.

# Name: Detect OverlapsForLinearEvents.py
# Description: Convert Roads and Highways Network Layer to Feature Layer and Detect Overlaps for Linear Events in a file geodatabase
# Requires: Esri Roads and Highways

# Import arcpy module
import arcpy

# Check out any necessary licenses
arcpy.CheckOutExtension("Highways")

# Local variables
network = r"C:\Data\NY_Data.gdb\LRSN_MilePoint"
event = r"C:\Data\NY_Data.gdb\LRSE_Speed_Limit"
overlaps_Output = r"C:\Data\Outputs.gdb\Gaps_Output"

# Process: Detect Overlaps for linear events
arcpy.env.overwriteOutput = 1
arcpy.DetectOverlapsForLinearEvents_locref(network, event, overlaps_Output)
