Calculate Visual Specifications (Production Mapping)

概要

Contains rules that determine the way features should be depicted. This tool assigns representation rules and builds calculated fields on features for symbolization and labeling using a predefined specification.

Learn more about visual specifications

使用法

• Multiple visual specifications can be applied to data layers.

• The visual specifications table contains all the available visual specifications you can apply to the data.

• The calculation of the visual specification adds fields to the target feature classes or tables. The number and names of the columns will vary but will include:

  • A field that holds the representation rule number
  • An override field associated with the representation to store symbol exception information
  • An optional new or existing field that holds calculated values

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

• The override field contains exception information on an individual representation.

• The calculated field contains the value that is produced as part of the selected specification.

パラメータ	説明	データ タイプ
input_layers [input_layers,...]	The feature layers, feature classes, or tables to which you want to apply the visual specifications.	Feature Layer ; Table
selected_only	Indicates whether only selected features from the input_layers parameter are processed. ALL_FEATURES —All features in the input_layers parameter are processed. This is the default. SELECTED_ONLY —Only selected features in the input_layers parameter are processed.	Boolean
input_vs_table_location	The location of the workspace that contains the visual specifications table. The VST_Specification table can be stored in a personal, file, or enterprise geodatabase.	Workspace
input_specifications [input_specifications,...]	The visual specifications you want to apply to the selected feature layers and feature classes.	String
show_representations	Indicates whether calculated representations in input_layers are displayed. SHOW —Displays calculated representations. This is the default. NO_SHOW —Does not display calculated representations.	Boolean
create_label_classes	Indicates whether calculated fields are displayed as labels. CREATE —Displays calculated fields as labels. This is the default NO_CREATE —Does not display calculated fields as labels	Boolean
preserve_free_representations	Indicates whether free representations are preserved when the Calculate Visual Specifications tool is run. PRESERVE —Preserves free representations (that is, they will not be removed when this tool is run). This is the default. NO_PRESERVE —Does not preserve free representations.	Boolean
output_layers （オプション）	Derived output parameter that represents the table after visual specifications have been calculated.	Table View

コード サンプル

CalculateVisualSpecification Example (Python Window)

The following ArcGIS Python window script calculates visual specifications on Production Mapping sample data.

# import the production mapping toolbox - you may have to alter this path
arcpy.ImportToolbox(r'C:\Program Files\ArcGIS\Desktop10.0\ArcToolbox\Toolboxes\Production Mapping Tools.tbx')

# paths to data
SoCal_ProductLibrary_gdb = "C:\\data\\SoCal_ProductLibrary.gdb"
RoadL = "C:\\data\\SoCal_Sample.gdb\\SoCal\\RoadL"
RoadL_Layer = "RoadL_Layer"

# make a feature layer and add it to the display
arcpy.MakeFeatureLayer_management(RoadL, RoadL_Layer)

# execute the calc visual spec
arcpy.CalculateVisualSpecification_production("RoadL_Layer", "ALL_FEATURES", SoCal_ProductLibrary_gdb, "'SoCal :: 1:250K specification'", "SHOW", "CREATE", "PRESERVE")
