Beschreibung

Computes the center point and radius of the smallest circle that contains a geometry. Returns a record with fields:

Use with ST_Collect to get the minimum bounding circle of a set of geometries.

To compute two points lying on the mimimum circle (the "maximum diameter") use ST_LongestLine.

Verfügbarkeit: 2.3.0
