Calculate Symbology

概要

Calculates representation symbology and field labels for nautical charts.

ArcGIS Maritime symbology tools are based on representations, which are the symbols that represent features and text fields in the map text display. The calculated representations and text fields use combinations of feature attributes to determine the symbols for particular features in a feature class.

使用法

  • INT 1 fields are calculated using a collection of rules that are managed in the INT1.cxml specification file in the following location:

    • For 32-bit Windows operating systems—<Install location>\Program Files\ArcGIS\MaritimeCharting\Desktop<version>\Common\Symbology
    • For 64-bit Windows operating systems—<Install location>\Program Files (x86)\ArcGIS\MaritimeCharting\Desktop<version>\Common\Symbology

  • The feature class representations must already exist in the geodatabase. Representations are added by updating nautical symbology.

  • Representation symbol information is managed in the INT1.Style file and is installed in the following location:

    • For 32-bit Windows operating systems—<Install location>\Program Files\ArcGIS\Desktop<version>\Styles
    • For 64-bit Windows operating systems—<Install location>\Program Files (x86)\ArcGIS\Desktop<version>\Styles

構文

arcpy.nautical.CalculateSymbology(selected_symbology, target_feature_classes, {preserve_free_representations})
パラメーター説明データ タイプ
selected_symbology

Specifies the ArcGIS Maritime visual specification that will be calculated.

  • All —INT1 and S-52 symbols will be calculated.
  • INT1 —The specification for symbols, abbreviations, and terms used on hard copy navigational charts will be calculated.
  • S-52 —The color and symbol specification for display of Electronic Navigational Charts (ENC) in an Electronic Chart Display and Information System (ECDIS) will be calculated.
String
target_feature_classes

The feature classes in which symbols will be calculated.

Feature Class; Feature Layer
preserve_free_representations
(オプション)

Specifies whether free representations will be preserved.

  • PRESERVE_FREE_REPRESENTATIONS —Free representations will be preserved; they will not be overwritten in any features. This is the default.
  • OVERWRITE_FREE_REPRESENTATIONS —Free representations will not be preserved; they will be overwritten in any features.
Boolean

コードのサンプル

CalculateSymbology example (Python window)

The following Python window script demonstrates how to use the CalculateSymbology function.

import arcpy, os, traceback

#Set workspace
arcpy.env.workspace = r'C:\Data\CalculateSymbologyTesting\ChartSchema.gdb'
prod_db = arcpy.env.workspace

#Nautical FDS path
naturalA = os.path.join(prod_db, "Nautical", "NaturalFeaturesA")

# Check for Production Mapping extension
if arcpy.CheckExtension("Foundation") == "Available":
    arcpy.CheckOutExtension("Foundation")
else:
    raise ex("Production Mapping license is unavailable.")

# Check for Nautical extension
if arcpy.CheckExtension("Nautical") == "Available":
    arcpy.CheckOutExtension("Nautical")
else:
    raise ex("Maritime: Charting license is unavailable.")


try:
	print "Running calculate symbology..."
	#Execute tool
	arcpy.CalculateSymbology_nautical("INT1",naturalA,"PRESERVE_FREE_REPRESENTATIONS")
	print "complete"

except ex, (instance):
	print "Error 1"
	arcpy.AddError(instance.parameter)

except arcpy.ExecuteError:
    # Get the geoprocessing error messages
	msgs = arcpy.GetMessage(0)
	msgs += arcpy.GetMessages(2)

	# Return gp error messages for use with a script tool
	arcpy.AddError(msgs)

except:
	# Get the traceback object
	tb = sys.exc_info()[2]
	tbinfo = traceback.format_tb(tb)[0]
	print tbinfo
