Résumé
Associates vertical (flight level) information from an airspace to two-dimensional features. Labeling these features with vertical information allows the display of three-dimensional information on a two-dimensional chart.
Discussion
This function creates new AirspaceArea features from Airspace features. A geometric union of overlapping airspace is performed. The geometric union creates features with identical horizontal extents but different vertical information (flight levels). These features can be stacked on top of each other. A new two-dimensional geometry is created from each group of stacked features. It writes that geometry and all vertical information from each group into a new feature in the AirspaceArea feature class. You can display the vertical information as annotation on a chart by using Custom Callouts with a VST expression. This allows you to show three-dimensional information on a two-dimensional chart.
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.
Syntaxe
CreateAirspaceAreas (aoi_info, production_database, preference_name)
| Paramètre | Explication | Type de données |
aoi_info | An AviationChartInfo object that contains the information for the 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. | AviationChartInfo |
production_database | Path to the workspace containing the data used for production tasks or referenced by maps and charts. | String |
preference_name | The preference used to run the create airspace areas in ArcMap. The preferences define the filter, airspace type, and spatial selection. | String |
