Buffer(DbGeography, Double)

Creates a geography value representing all points less than or equal to distance from the given DbGeography value.

public:
 abstract System::Data::Spatial::DbGeography ^ Buffer(System::Data::Spatial::DbGeography ^ geographyValue, double distance);

public abstract System.Data.Spatial.DbGeography Buffer (System.Data.Spatial.DbGeography geographyValue, double distance);

abstract member Buffer : System.Data.Spatial.DbGeography * double -> System.Data.Spatial.DbGeography

Public MustOverride Function Buffer (geographyValue As DbGeography, distance As Double) As DbGeography

Parameters

geographyValue

DbGeography

The geography value.

distance

Double

A double value specifying how far from geographyValue to buffer.

Returns

DbGeography

A new DbGeography value representing all points less than or equal to distance from geographyValue.
