Map Projections

Cute! Although I’m guessing that people who really are into maps have a slightly higher view of Mercator than he implies. Cheers, -Isaac

PASS Wrap-Up

Hi Folks, I just wrapped up my talk the 2011 PASS Summit. Here are a few quick thoughts: StreamInsight seems like a technology that could benefit a large number of customers, for a large number of scenarios. But relatively few people even know what SI can do. So although the title of my talks was,…

To answer one question he asks in his post: StreamInsight doesn’t require SQL Server Compact, but if you use it for you use it for…

Filter: One Odd Duck

Spatial Data Type Structure

Hi Folks, As part of a larger effort to document our protocols, SQL Server has just released documentation on the structure of our spatial types.  The document is also available in PDF.  Note that all of this is preliminary, and while I doubt it will change much, it could.  I had very little to do…
