GeoBoundingBox() is used to aggregate a geometry into an area and calculate the smallest bounding box that contains all coordinates.
A GeoBoundingBox is represented as a list of four values: left, right, top, bottom.
Syntax:
GeoBoundingBox(field_name)
Return data type: string
Arguments:
| Argument | Description |
|---|---|
| field_name | A field or expression referring to a field containing the geometry to be represented. This could be either a point (or set of points) giving longitude and latitude, or an area. |
GeoBoundingBox() aggregates a set of geometries and returns four coordinates for the smallest rectangle that contains all the coordinates of that aggregated geometry.
To visualize the result on a map, transfer the resulting string of four coordinates into a polygon format, tag the transferred field with a geopolygon format, and drag and drop that field into the map object. The rectangular boxes .will then be displayed in the map visualization.
