Spatial Data Types

• Geography (Geodetic)• Geometry (Planar)

2 Spatial Datatypes

• Ellipsoidal coordinate support only (e.g. WGS 84)• Core set of geospatial methods• No OGC/ISO standards compliance (though many standards components are there)

• Geospatial index• Designed as a simple, straight-forward geospatial implementation

Geography

• Planar coordinate support only (georeferenced and non-georeferenced)

• Complete set of spatial methods• OGC/ISO standards compliance (OGC SFS v1.1, ISO 19125)• Spatial index• Comprehensive spatial/geospatial offering supporting 2D planimetric

Overview of New Spatial Features in SQL Server 2012

• Spatial Index Improvements

• Spatial Type Improvements

• Performance Improvements

• Other Spatial Improvements

Circular Arcs

• New Keywords: CircularStrings CompoundCurves CurvePolygons

• Supported in WKT, WKB and GML

• Supported in both geometry and geography types

• Based on SQL MM Spatial (Part 3) Standard

Circular ArcsGeography Type Considerations

LINESTRING (0 50, 90 50, 180 50, 270 50, 0 50)

CIRCULARSTRING (0 50, 90 50, 180 50, 270 50, 0 50)

Linestring segments in the geography type define theminimum distance path on theunderlying ellipsoid.

Circularstring segments in the geography type define a circularpath. A good example is a latitude parallel.

Circular ArcsGeography Type Considerations

CIRCULARSTRING (0 50, 90 50, 180 50, 270 50, 0 50)

CURVEPOLYGON (CIRCULARSTRING (0 50, 90 50, 180 50, 270 50, 0 50))

If a circular linestring is closed, a curve polygon can be created

Coordinate pair order is importantfor the geography type. This setof coordinates is ordered accordingto the “left foot rule” for exteriorrings.

New Methods for Circular Arcs

BufferWithCurves()

DECLARE @g GEOGRAPHY = GEOGRAPHY::STGeomFromText('CIRCULARSTRING(0 50, 45 50, 90 50)',4326)DECLARE @b GEOGRAPHY = @g.BufferWithCurves(500000)SELECT @b.STNumPoints()--Number of vertices: 11

DECLARE @g GEOGRAPHY = GEOGRAPHY::STGeomFromText('CIRCULARSTRING(0 50, 45 50, 90 50)',4326)DECLARE @b GEOGRAPHY = @g.STBuffer(500000)SELECT @b.STNumPoints()--Number of vertices: 257

This method will construct theresulting polygon with circular arcs, often resulting in a dramatically smaller spatialobject.

Existing Methods And Circular Arcs

All existing method work on circular arcs

STIntersects() example

Improved precision

All constructions and relations are now done with 48 bits of precision in SQL Server 2012, compared to 27 bits used in SQL Server 2008 and 2008 R2.

For example, consider the following coordinate which was processed using the STUnion() method in SQL Server 2008

-82.339025999885052 29.662144999951124                -82.339026 29.661245

Original Coordinate New Coordinate

In Denali, the greater numerical precision typically maintains the precision of the original coordinates. Here is the result of the same STUnion() method in Denali, as above

82.339026 29.661245                -82.339026 29.661245

On March 20, 2010, the trimaran, Groupama 3, became the fastest boat to circumnavigate the Earth non-stop, ever (including power boats)… in 48 days, 7 hours and 44 minutes…

…and of course, it’s GPS-equipped…

Spatial Helper Stored Procedures

Two new helper methods are available:

• sp_help_spatial_geography_histogram• sp_help_spatial_geometry_histogram They can be used for investigating spatial index efficiency or analyzing spatial data in general. The histograms could be also shown on a SSMS map.

The data can be used for external visualization:
