On February 24 (that’s this Wednesday!) at 8AM Pacific Standard Time, we’ll begin kicking on a series of web casts to illustrate the technologies within and around the Bing Maps Server. There are currently 3 web casts scheduled as follow which dive deep into the solution as a whole, IT requirements and infrastructure, and developer aspects respectively. If you’re at all interested in the Bing Maps Server as an offline server solution for your geospatial mapping needs put all of these on your calendar.
