Create JOG Elevation Tint Bands from Features

Zusammenfassung

Converts contour polylines into elevation tint band polygon features. The features can be used to represent different elevation levels on a Joint Operations Graphic (JOG).

Verwendung

  • Use contour lines that have been collected using meters.

  • The feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters must all contain the field listed in the Contour Elevation Field parameter.

  • The Elevation Units parameter value applies to all the feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters.

  • This tool may generate holes around the corners of AOI Feature Class features. Set a high AOI Buffer value to correct this. Do not use a negative value for this parameter.

Syntax

arcpy.defense.CreateJOGElevationTintBands(AOI_Feature_Class, AOI_Field, AOI_Buffer, Contour_Feature_Class, Contour_Elevation_Field, Contour_Elevation_Units, Output_Feature_Class, Output_Feature_Class_Units, {Exclusion_Feature_Classes})
ParameterErklärungDatentyp
AOI_Feature_Class

The area of interest for the JOG. This feature is typically stored in an index feature class.

Feature Layer
AOI_Field

Ein Feld, das eine eindeutige Kennung für jeden Interessenbereich enthält.

Field
AOI_Buffer

Ein Puffer, der auf die Features von Eingabe-Interessenbereichen angewendet wird. Der Puffer dehnt die Geometrie der AOI-Feature-Class aus, um die Features in die Konturlinien-Feature-Class einzubeziehen, die außerhalb der Grenze eines AOI liegen. Dadurch kann die Genauigkeit der Bandberechnung zum Erstellen von Polygonen verbessert werden.

Linear unit
Contour_Feature_Class

The feature layer that contains the contours. The information for the output bands will be derived from these features. This must be a polyline feature class.

Feature Layer
Contour_Elevation_Field

The field in the contour feature layer from which the elevation values will be derived.

Field
Contour_Elevation_Units

The unit of measurement that has been used to collect the contours and exclusion features.

  • METERS —The contours and exclusion features have been collected using meters. This is the default.
  • FEET —The contours and exclusion features have been collected using feet.
String
Output_Feature_Class

The feature class that will contain the banding features.

Feature Class
Output_Feature_Class_Units

Output band distance units.

  • METERS —Units in meters.
  • FEET —Units in feet.
String
Exclusion_Feature_Classes
[Exclusion_Feature_Classes,...]
(optional)

Feature layers that define areas for processing exclusion. Excluded areas will not be taken into account when calculating the percent area ratio for the output bands.

CreateJOGElevationTintBands example (stand-alone script)

The following stand-alone script demonstrates how to use the CreateJOGElevationTintBands tool.

# Name: CreateJOGElevationTintBands_Example.py
# Description: Create banding features from a single JOG feature
# Requirements: ArcGIS Defense Mapping solution

# Import arcpy module
import arcpy

# Check out a DefenseMapping extension license
arcpy.CheckOutExtension("defense")
arcpy.CheckOutExtension("foundation")

# set the gp environment
arcpy.env.workspace = "c:\\data\\MapIndex.gdb"
arcpy.env.overwriteOutput = "true"

# create a feature layer for the AOI_Feature_Class parameter
aoiPath = "MapIndex\\JOG_Index"
arcpy.MakeFeatureLayer_management(aoiPath,"aoiFeatures")
print arcpy.GetMessages()

# create a feature layer for the Contour_Feature_Class parameter
contoursPath = "ContourL"
arcpy.MakeFeatureLayer_management(contoursPath,"contourFeatures")
print arcpy.GetMessages()

# create a where clause for select by layer
whereClause = "NRN='1501ANI1105'"

# select a single AOI feature from JOG
arcpy.SelectLayerByAttribute_management("aoiFeatures","NEW_SELECTION",whereClause)
print arcpy.GetMessages()

# Variables for the tool
aoiField = "NRN"
aoiBuffer = "100 meters"
contourElevField = "elevation"
outputFeatureClass = "jogElevTintBands"

# execute the Create JOG Elevation Tint Bands tool - output is written arcpy.env.workspace
arcpy.CreateJOGElevationTintBands_defense("aoiFeatures", aoiField, aoiBuffer, "contourFeatures", contourElevField, "Meters", outputFeatureClass, "Meters","")
print arcpy.GetMessages()

# Check in the Defense Mapping extension
arcpy.CheckInExtension("defense")
arcpy.CheckInExtension("foundation")
