OGC GeoPackage Tiles Reader Parameters

Specifies the zoom level that will be used when reading the GeoPackage Tiles tile data.

The default is the maximum possible resolution zoom level.

This parameter allows you to choose different naming schemes for a feature type, and the number of feature types generated for the reader. The Feature Type Name changes, depending on the selection.

The GeoPackage standard requires that all foreign key values in a GeoPackage database are valid (see Requirement 7 of the specification).

• Yes (default): The reader will ensure that all foreign key values in the database are valid before reading any data. If any foreign keys are invalid then the translation will fail.
• No: The reader will attempt to read the data without performing any foreign key checks.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Specifies the coordinate system of the search envelope if it is different than the coordinate system of the data. The coordinate system associated with the data to be read must always be set if this parameter is set.

If this parameter is set, the minimum and maximum points of the search envelope are reprojected from the Search Envelope Coordinate System to the reader’s coordinate system prior to applying the envelope.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario, you can use this parameter to expose additional attributes on multiple feature types.
