描述
Generates line data from airspace features. You use this data to generate symbology and labels for both sides of the line features.
讨论
This function creates line data from airspace features that can be used for creating symbology and labeling both sides of coincident airspace features. The line features have attribute values from the source airspaces. Using visual specifications, you can symbolize and label the lines based on these attributes. This will depict the types of airspace line features you can create. The features are written to the AirspaceLine feature class.
Preferences are a configuration step. You must set them before running the tool. However, once they are set, you do not have to change them unless you want to. You can create multiple sets of preferences by assigning names to them and switching between them.

CreateAirspaceLines (aoi_info, production_database, preference_name)
| 参数 | 说明 | 数据类型 |
aoi_info [aoi_info,...] | A list of AviationChartInfo objects. The objects contain the information for map ID for the areas of interest to be processed. The map ID can be retrieved using the GetAviationAOI function and will be formatted as Solution Name::Product Class Name::Series Name::Product Name::Instance Name::AOI Name. | String |
production_database | Path to the workspace containing the data used for production tasks or is referenced by maps and charts. | String |
preference_name | The preference used to run the create airspace lines in ArcMap. The preferences define the airspace type, label fields, and cluster tolerance. | String |
