Import From GIFD/TGD (Defense Mapping)
Récapitulatif
Imports feature-level metadata from Geospatial Intelligence Feature Database (GIFD) or Theatre Geospatial Database (TGD) geodatabases to the Topographic Features Data Management (TFDM) DatasetSrf and CollectionSrf feature classes.
Utilisation
DatasetSrf must exist in the TFDM geodatabase.
Before importing GIFD or TGD metadata, GIFD or TGD data should be split along the TFDM DatasetSrf boundaries.
-
DatasetSrf features are updated based on the GIFD or TGD features that they contain. All feature classes in the GIFD or TGD data model have common metadata attributes. Some of the metadata values are hard-coded and some are mapped. For the mapped attributes, many GIFD or TGD values need to be considered for mapping to a single value in a DatasetSrf feature. To do this, statistics are compiled per DatasetSrf feature. For each attribute that is mapped, the majority value from the compiled statistics is used.

Syntaxe
| Paramètre | Explication | Type de données |
in_workspace |
The workspace that stores the GIFD or TGD features. Feature-level metadata from this workspace will be exported to the TFDM DatasetSrf and CollectionSrf feature classes. | Workspace |
in_dataset_areas | The DatasetSrf features to which the importer will write GIFD or TGD feature-level metadata. The tool also writes feature-level metadata to CollectionSrf features from the same workspace that stores in_dataset_areas features. | Feature Layer |
Exemple de code
The following script executes the ImportGIFDTGDMetadata function. This function updates attribute values of TFDM Features that intersect GIFD or TGD features.
