Create JOG Elevation Tint Bands from Features

Résumé

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).

Utilisation

• 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.

Syntaxe

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})

Paramètre	Explication	Type de données
AOI_Feature_Class	The area of interest for the JOG. This feature is typically stored in an index feature class.	Feature Layer
AOI_Field	Champ qui contient un identifiant unique pour chaque zone d'intérêt.	Field
AOI_Buffer	Zone tampon à appliquer aux entités en entrée d'une zone d'intérêt. La zone tampon développe la géométrie Classe d'entités AOI de façon à inclure les entités dans la classe d'entités des isolignes qui se trouvent au-delà de la limite d'une zone d'intérêt (AOI). Ceci peut améliorer la précision du calcul d'étirement qui est utilisé pour générer des polygones.	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,...] (Facultatif)	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.	Feature Layer
