Résumé
Retrieves the map ID, reference scale, rotation angle, geometry, and extraction query information for an area of interest (AOI) feature.
Discussion
This function can be used to retrieve the AOIs for different aeronautical charts stored in a product library. Once this information is retrieved, you can view specific details about an AOI feature, such as the map ID, reference scale, rotation angle, geometry, and extraction query. For instance, you can view the spatial reference and rotation angles for all the AOIs in the product library to ensure they are all consistent across products.
Syntaxe
GetAviationAOI (product_library, map_id)
| Paramètre | Explication | Type de données |
product_library | The path to a connection file or the database used as the product library workspace. | String |
map_id | The path to the area of interest in the product library. The path information is formatted as Solution Name::Product Class Name::Series Name::Product Name::Instance Name::AOI Name. | String |
Valeur renvoyée
| Type de données | Explication |
| Dictionary | A dictionary that contains the map ID, reference scale, rotation angle, spatial reference, and extraction query properties. |
