DefaultCoordinateSystemId | Gets the default coordinate system id (SRID) for geography values (WGS 84). | |

Dimension | Gets the dimension of the given DbGeography value or, if the value is a collections, the largest element dimension. | |

ElementCount | Gets the number of elements in this DbGeography value, if it represents a geography collection. <returns>The number of elements in this geography value, if it represents a collection of other geography values; otherwise | |

Elevation | Gets the elevation (Z coordinate) of this DbGeography value, if it represents a point. <returns>The elevation (Z coordinate) value of this geography value, if it represents a point; otherwise | |

EndPoint | Gets a DbGeography value representing the start point of this value, which may be null if this DbGeography value does not represent a curve. | |

IsClosed | Gets a nullable Boolean value indicating whether this DbGeography value is closed, which may be null if this value does not represent a curve. | |

IsEmpty | Gets a nullable Boolean value indicating whether this DbGeography value is empty. | |

Latitude | Gets the Latitude coordinate of this DbGeography value, if it represents a point. <returns>The Latitude coordinate value of this geography value, if it represents a point; otherwise | |

Length | Gets a nullable double value that indicates the length of this DbGeography value, which may be null if this value does not represent a curve. | |

Longitude | Gets the Longitude coordinate of this DbGeography value, if it represents a point. <returns>The Longitude coordinate value of this geography value, if it represents a point; otherwise | |

Measure | Gets the M (Measure) coordinate of this DbGeography value, if it represents a point. <returns>The M (Measure) coordinate value of this geography value, if it represents a point; otherwise | |

PointCount | Gets the number of points in this DbGeography value, if it represents a linestring or linear ring. <returns>The number of elements in this geography value, if it represents a linestring or linear ring; otherwise | |

ProviderValue | Gets a representation of this DbGeography value that is specific to the underlying provider that constructed it. | |

SpatialTypeName | Gets the spatial type name of the DBGeography. | |

StartPoint | Gets a DbGeography value representing the start point of this value, which may be null if this DbGeography value does not represent a curve. | |

WellKnownValue | Gets or sets a data contract serializable well known representation of this DbGeography value. |
