Generate HLZ Suitability (Intelligence)—ArcGIS Pro

Summary

Creates a helicopter landing zone (HLZ) suitability raster layer from reclassified slope, reclassified land cover, and obstacle buffers.

Usage

Use the Slope Reclassify (Degrees) raster function to create the Input Slope Raster parameter.
Use the GeoCover Reclassify or NLCD Reclassify raster function to generate the Input Land Cover Raster parameter.
Use the DOF To Obstacle Features or Generate Obstacle Features tool to create the Input Obstacle Buffer Features parameter.
The Output Raster parameter will contain the following values:
Value Description
1
Acceptable
2
Acceptable with caution
3
Obstacle interference

Value	Description
1	Acceptable
2	Acceptable with caution
3	Obstacle interference

Parameters

Label	Explanation	Data Type
Input Slope Raster	The reclassified slope raster with values 1 (acceptable) and 2 (acceptable with caution). All other values will be excluded from the analysis.	Raster Layer
Input Land Cover Raster	The reclassified land cover raster with values 1 (acceptable) and 2 (acceptable with caution). All other values will be excluded from the analysis.	Raster Layer
Input Obstacle Buffer Features	Obstacle area features representing approach and departure safety buffers around obstacles.	Feature Layer
Output Raster	The output raster dataset.	Raster Dataset

arcpy.intelligence.GenerateHLZSuitability(in_slope_raster, in_land_cover_raster, in_obstacle_buffer_features, out_raster)

Name	Explanation	Data Type
in_slope_raster	The reclassified slope raster with values 1 (acceptable) and 2 (acceptable with caution). All other values will be excluded from the analysis.	Raster Layer
in_land_cover_raster	The reclassified land cover raster with values 1 (acceptable) and 2 (acceptable with caution). All other values will be excluded from the analysis.	Raster Layer
in_obstacle_buffer_features	Obstacle area features representing approach and departure safety buffers around obstacles.	Feature Layer
out_raster	The output raster dataset.	Raster Dataset

Code sample

GenerateHLZSuitability example 1 (stand-alone script)

The following Python script demonstrates how to use the GenerateHLZSuitability function in a stand-alone script.

import os
import arcpy

working_mty = r"d:\working\monterey"
slope = os.path.join(working_mty, "results.gdb", "ned_reclass_10m")
lcover = os.path.join(working_mty, "results.gdb", "nlcd_reclass_10m")
obx_buf = os.path.join(working_mty, "results.gdb", "obx_buffers")
mty_suit = os.path.join(working_mty, "results.gdb", "monterey_hlz")
arcpy.intelligence.GenerateHLZSuitability(slope, lcover, obx_buf, mty_suit)

GenerateHLZSuitability example 2 (Python window)

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

import arcpy
arcpy.intelligence.GenerateHLZSuitability("d:/working/monterey/working_mty/results.gdb/ned_reclass_10m", 
                                          "d:/working/monterey/working_mty/results.gdb/nlcd_reclass_10m", 
                                          "d:/working/monterey/working_mty/results.gdb/obx_buffers", 
                                          "d:/working/monterey/working_mty/results.gdb/monterey_hlz")
