Spatial queryPro tier

bbox_of

Geographic bounding box of any qualified table's geometry column. Quick way to scope downstream queries — pass the result to density_grid or use it to confirm a layer covers the area you care about.

Use cases

Confirm that a dataset actually covers your area of interest before querying.
Auto-scope a density_grid call to the natural extent of a layer.
Build a UI that shows each layer's coverage on a map.

Arguments

Name	Type	Required	Description
qualified_table	string	required	Schema-qualified table name.
geom_column	string	optional	Geometry column. Default `geometry`.
