License Level:BasicStandardAdvanced

Summary

Checks routes on the network for gaps between linear events.

Usage

Syntax

DetectGapsForLinearEvents_roads (in_network, in_event, out_feature, {in_tvd}, {in_from_measure}, {in_to_measure}, {in_tolerance})
ParameterExplanationData Type
in_network

The network containing the linear event features to be checked for gaps.

Feature Layer
in_event

The linear event features to be checked for gaps.

Feature Layer
out_feature

The output feature class containing lines where there are gaps between events.

Feature Class
in_tvd
(Optional)

The temporal view date for the network.

Date
in_from_measure
(Optional)

Defines the lower bound of the portion of the route on which gaps will be detected.

Double
in_to_measure
(Optional)

Defines the upper bound of the portion of the route on which gaps will be detected.

Double
in_tolerance
(Optional)

Tolerance, in LRM (Linear Referencing Method) units, used to compare events on routes.

Double

# Name: Detect Measures Out of Range.py
# Description: Convert Roads and Highways Network Layer to Layer and Detect Measures Out Of Range for Events in a file geodatabase
# Requires: Esri Roads and Highways Solution

# 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"
gaps_Output = r"C:\Data\Outputs.gdb\Gaps_Output"

# Process: Detect Gap for linear events
arcpy.env.overwriteOutput = 1
arcpy.DetectGapsForLinearEvents_roads(network, event, gaps_Output)
