We have just released a white paper, New Spatial Features in SQL Server Code-Named “Denali” Community Technology Preview 1, as your definitive guide to the spatial improvements in this release of SQL Server.
Of course, you can’t take advantage of the new spatial features without the new server. You can now download the new server, Microsoft SQL Server code-named 'Denali' - Community Technology Preview 1 (CTP1), today.
Also, don’t forget that the serialization format for the spatial types has been updated in Microsoft SQL Server CLR Types Serialization Formats [MS-SSCLRT] for those of you who need to know even more.
Let us know how you like the new spatial features.
