It's good to see Ed Katibah open up a blog on SQL Server spatial data. Ed is sort of the "dad" of spatial data in SQL Server; he's got a ton of experience and history in this space. Be sure to catch his posting on what's new in spatial for CTP6.  I've been trying out the new functions and the more I use the spatial types and functions, the more I understand the reasoning behind the dual Geometry - Geography types in SQL Server.

Issac's back at blogging too about spatial indexes, really makes for good reading.
