Calculate Representation Fields

摘要

Defense Mapping configuration tool that calculates representation symbology to the input features. This tool calculates symbology for many layers and links feature attributes to representation rules and label expressions.

用法

  • You can calculate multiple visual specifications to multiple input feature layers.

  • The Input Visual Specifications Workspace contains the visual specifications you can apply to input features.

  • This tool calculates fields for the input features. The number and names of the fields will vary but will include the following:

    • A field that holds the representation rule number. This is known as the representation rule field.
    • An Override field associated with the representation to store symbol exception information. The Override field contains exception information on an individual representation.
    • An optional new or existing field that holds calculated values. The Calculated Values field contains the value that is produced as part of the selected specification.

  • The Representation Rule field contains the number of the symbol being used for the feature class in association with feature class representations.

语法

CalculateRepresentationFields_defense (in_features, in_visual_spec_workspace, in_specs)
参数说明数据类型
in_features
[in_features,...]

The feature classes for which you want the visual specifications field calculated.

Feature Layer
in_visual_spec_workspace

The location of the workspace that contains the visual specifications table (VST_Specification). This table can be stored in a personal, file, or enterprise geodatabase.

Workspace
in_specs
[in_specs,...]

The visual specifications you want to apply to the selected feature layers and feature classes.

CalculateRepresentationFields example (Python window)

The following code example demonstrates how to execute the CalculateRepresentationFields function.

# Set up input features, visual specification database, and specification
features = "C:/Example/example.gdb/MGCP/AerofacA;C:/Example/example.gdb/MGCP/AerofacP;C:/Example/example.gdb/MGCP/AgristrA;C:/Example/example.gdb/MGCP/AgristrP"
visualSpecification = "C:/Program Files (x86)/ArcGIS/EsriDefenseMapping/Desktop10.4/Mgcp/Cartography/Symbology/MGCP_TRD_4_3_MTM_Visual_Specification.mdb"
specification = "'MGCP_50K :: MGCP TRD 4.3 Visual Specification for MGCP Topographic Map (MTM)'"

# Running Calculate Representation Fields tool
arcpy.CalculateRepresentationFields_defense(features, visualSpecification, specification)
