概要
Generates polygon masks for annotation features that intersect other polyline features. This tool supports nautical cartographic workflows that require masking based on geographic coincidence to specified input features. The specified input features (those that intersect the input annotation features) are polylines from the ArcGIS Maritime data model or other sources.
This tool is a model that increases productivity in creating and updating cartographic data for digital and hard-copy nautical charts.
使用法
Each layer in Intersecting Layers is used to select intersecting annotation features in Input Annotation Layer. Polygon masks are generated around the selected annotation features.
If no features in Input Annotation Layer are selected, Output Mask Layer will be empty.
Use a positive number in the Margin parameter. A negative number will create smaller masks in Output Mask Layer. This will diminish the cartographic effect of the mask on your chart.
The objectid value of each Input Annotation Layer feature is written to Output Mask Layer.

| パラメーター | 説明 | データ タイプ |
Input_Annotation_Layer | The annotation layer from which masks will be created. | Feature Layer |
Intersecting_Layers [Intersecting_Layers,...] | Masks are generated for annotations that intersect features in these layers. | Feature Layer |
Margin | Specifies a space, in page units, that surrounds the Input Annotation Layer features used to create the mask polygons. The default value is 1 point. | Linear Unit |
Calculation_coordinate_system | The spatial reference of the map in which the masking polygons will be used. This spatial reference is not assigned to the Output Mask Layer. | Spatial Reference |
Reference_Scale | Scale used to calculate masking geometry. | Double |
Output_Mask_Layer | The output feature class that will contain the mask features. The tool creates this feature class. | Feature Class |

GenerateAnnotationMasks example (stand-alone script)
The following stand-alone script demonstrates how to use the GenerateAnnotationMasks tool.

# Description: Creates annotation masks around anno features that intersect input polygons.

inAnno = r'c:\data\nautical.sde\Micklefirth.DBO.Nautical\Micklefirth.DBO.AidsToNavigationPAnno'
res = arcpy.MakeFeatureLayer_management(inAnno,'inAnno')
inAnnoLayer = res.getOutput(0)
# create a list of intersecting layers
intersectLayers = r'c:\data\nautical.sde\Micklefirth.DBO.Nautical\Micklefirth.DBO.DepthsA'
# masking size
