SQLite MBTiles Reader Parameters
Dataset Parameters
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.
Value |
Feature Type Name |
Example |
---|---|---|
From Format Name | <reader_type_name> | MBTILES |
From File Name | <filename> | file |
Specifies the zoom level that will be used when reading the MBTiles tile data.
This parameter contains the following options:
- Source Data Bounds: The Bounds metadata item is read from the MBTiles file and used as the spatial filter.
- Search Envelope: Enables the Use Search Envelope parameter. The minimum and maximum x and y parameters define a Spatial Filter for the input features. You can also specify a coordinate system that applies to the values in the box. The x and y values are initially set to EPSG:3857 Spherical Mercator.
- None: No spatial filter will be used.
Only features that intersect with the Spatial Filter are returned.
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.
Schema Attributes
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.
