Create TLM Elevation Guide Bands (Defense Mapping)

Zusammenfassung

Creates banding features that can be used to generate the Elevation Guide Box element for a Topographic Line Map (TLM).

Verwendung

Syntax

CreateTLMElevationGuideBands_defense (AOI_Feature_Class, Contour_Features, Contour_Interval, Elevation_Field_Name, Elevation_Units, Output_Feature_Class, {Additional_Elevation_Features}, {Exclusion_Feature_Classes})
ParameterErläuterungDatentyp
AOI_Feature_Class

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

Feature Layer
Contour_Features

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_Interval

The range in elevation (distance) between contour features. This must be 10, 20, 40, or 80. The default value is 20.

Long
Elevation_Field_Name

The field within the contour feature layer from which the elevation values will be derived. The default value for this is ZV2.

String
Elevation_Units

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

  • METERSThe contours and additional elevation features have been collected using meters. This is the default value.
  • FEETThe contours and additional elevation features have been collected using feet.
String
Output_Feature_Class

The feature class that will contain the banding features. The default name is TLM<scale>_CreateTLMElevationGuide.

Feature Class
Additional_Elevation_Features
(optional)

Feature layers that contain additional elevation information that can be used during band creation.

Feature Layer
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. When excluding open water areas for coastal sheets, it is necessary to include these features as additional elevation features as well.

CreateTLMElevationGuideBand example (stand-alone Python script)

In this Python example, elevation bands are created over the V695X2549 feature in the TLM index.
