SqlSpatialFunctions Class
Contains function stubs that expose SqlServer methods in Linq to Entities.
Assembly: EntityFramework.SqlServer (in EntityFramework.SqlServer.dll)
Name | Description | |
---|---|---|
![]() ![]() | AsTextZM(DbGeography) | Returns the Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation of a geography instance augmented with any Z (elevation) and M (measure) values carried by the instance. |
![]() ![]() | AsTextZM(DbGeometry) | Returns the Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation of a geography instance augmented with any Z (elevation) and M (measure) values carried by the instance. |
![]() ![]() | BufferWithTolerance(DbGeography, Nullable<Double>, Nullable<Double>, Nullable<Boolean>) | Returns a geometric object representing the union of all point values whose distance from a geography instance is less than or equal to a specified value, allowing for a specified tolerance. |
![]() ![]() | BufferWithTolerance(DbGeometry, Nullable<Double>, Nullable<Double>, Nullable<Boolean>) | Returns a geometric object representing the union of all point values whose distance from a geometry instance is less than or equal to a specified value, allowing for a specified tolerance. |
![]() ![]() | EnvelopeAngle(DbGeography) | Returns the maximum angle between the point returned by EnvelopeCenter() and a point in the geography instance in degrees. |
![]() ![]() | EnvelopeCenter(DbGeography) | Returns a point that can be used as the center of a bounding circle for the geography instance. |
![]() ![]() | Filter(DbGeography, DbGeography) | Offers a fast, index-only intersection method to determine if a geography instance intersects another SqlGeography instance, assuming an index is available. |
![]() ![]() | Filter(DbGeometry, DbGeometry) | Offers a fast, index-only intersection method to determine if a geography instance intersects another SqlGeometry instance, assuming an index is available. |
![]() ![]() | InstanceOf(DbGeography, String) | Tests if the SqlGeography instance is the same as the specified type. |
![]() ![]() | InstanceOf(DbGeometry, String) | Tests if the SqlGeometry instance is the same as the specified type. |
![]() ![]() | MakeValid(DbGeometry) | Converts an invalid geometry instance into a geometry instance with a valid Open Geospatial Consortium (OGC) type. |
![]() ![]() | NumRings(DbGeography) | Returns the total number of rings in a Polygon instance. |
![]() ![]() | PointGeography(Nullable<Double>, Nullable<Double>, Nullable<Int32>) | Constructs a geography instance representing a Point instance from its x and y values and a spatial reference ID (SRID). |
![]() ![]() | PointGeometry(Nullable<Double>, Nullable<Double>, Nullable<Int32>) | Constructs a geometry instance representing a Point instance from its x and y values and a spatial reference ID (SRID). |
![]() ![]() | Reduce(DbGeography, Nullable<Double>) | Returns an approximation of the given geography instance produced by running the Douglas-Peucker algorithm on the instance with the given tolerance. |
![]() ![]() | Reduce(DbGeometry, Nullable<Double>) | Returns an approximation of the given geography instance produced by running the Douglas-Peucker algorithm on the instance with the given tolerance. |
![]() ![]() | RingN(DbGeography, Nullable<Int32>) | Returns the specified ring of the SqlGeography instance: 1 ≤ n ≤ NumRings(). |
