...

geoBuffer( geometryValue, Distance,  decimalPlaces, quadrantSegments )

ArgumentTypeDescription
geometryValue

WTK String or

Geometry Object

The geometry the calculation is formed around provided in either data type.

DistanceFloatThe size of the buffer area to be used.
decimalPlacesIntegerThe number of decimal places to use in the geometry calculations. Defaults to 0 if not provided. Can also take negative values e.g. -1 uses geometry to the nearest 10.
quadrantSegmentsIntegerThe number of line segments used to represent the quadrant of a circle where the buffer boundary contains circular arcs. Defaults to 8 if not provided.

Examples

geoBuffer("POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10))", 10)

Returns a geometry Geometry of the buffer area.
