Here's a couple of new Virtual Earth articles. First is this good one from Jonathan Hawkins on how he built a mashup of US national parks using Virtual Earth and Altas, the Microsoft's Ajax framework. Detailed step-by-step instructions with lots of code and screenshots. The second is this article from MP2K Magazine interviewing the folks from Fresh Logic Studios, creators of the slick Virtual Earth mashup they call Atlas. I will be updating the /howto guide by next week with these and a variety of other good articles that have come-in over the past month. Actually, next week I'll be updating the whole site.
