Analyze LAS Runway Obstacles

Zusammenfassung

Analyzes lidar data and Obstruction Identification Surfaces (OIS) to determine if lidar points are penetrating.

Verwendung

  • The Input OIS Features parameter must be a multipatch feature class that contains the OIS.

  • The Input LAS Obstacles parameter is a lidar (LAS) dataset.

  • A point feature is generated, and output for each lidar point that falls within the area is covered by the OIS, where the height of that point exceeds the height of the OIS feature at that point. The x and y point coordinates are the same as the lidar point with which the output point is associated.

    Delta Z

  • This tool requires an Erweiterung "ArcGIS 3D Analyst" license.

  • The optional output LAS files will match the LAS version, point record format, and compression of the input.

  • The optional LAS files and LAS dataset file will overwrite any files found that share the same names.

  • When specified to generate the LAS output, LAS file generated containing the lidar points from the input penetrating the OIS surface.

Syntax

AnalyzeLASRunwayObstacles(in_ois_features, in_las_obstacles, {out_obstacle_feature_class}, {target_folder}, {out_las_obstacles})
ParameterErklärungDatentyp
in_ois_features

The input multipatch features representing one or more OIS. The feature class must be z-enabled.

Feature Layer
in_las_obstacles

The input LAS dataset that contains 3D data points covering the area around an airport. The points represent a 3D view of natural and man-made objects that could pose a hazard to flight.

LAS Dataset Layer
out_obstacle_feature_class
(optional)

The output point features that represent lidar points in OIS features in which the height of the lidar point is greater than the height of the enclosing OIS feature at that point. This feature class is required output only if no output LAS dataset is requested.

Feature Class
target_folder
(optional)

The folder to which LAS files will be written. Each output file will have the same LAS file version and point record format as the input file. This folder is required output only if no output feature class is requested.

Folder
out_las_obstacles
(optional)

The output LAS dataset referencing the newly created LAS files. This LAS Dataset is created only when the output folder is specified to generate the LAS output.

LAS Dataset

AnalyzeLASRunwayObstacles example (stand-alone script)

The following Python window script demonstrates how to use the AnalyzeLASRunwayObstacles tool.

import arcpy

#set gp environment
arcpy.CheckOutExtension("Airports")
arcpy.CheckOutExtension("3D")

# Input Obstruction Identification Surface Feature Class
inOISFeatures = r"C:\data\ois.gdb\ObstructionIdSurface"

# Input LAS Obstacle Data
inLASObstacles = r"C:\data\PotentialObstacles.lasd"

# Feature class that will contain the output obstacles
outObstacleFeatures = r"C:\data\ois.gdb\ActualObstacles"

# Processing AnalyzeLASRunwayObstacles
arcpy.AnalyzeLASRunwayObstacles_aviation(inOISFeatures, inLASObstacles, outObstacleFeatures)

# Folder that will contain the LIDAR output
outObstacleFolder = r"C:\data\LasObstacles"

# Output LIDAR dataset
outObstacleDataset = r"C:\data\LasObstacles\LasObstacles.lasd"

# Processing AnalyzeLASRunwayObstacles
