BDC Mapper Web Part? How about a free way to map your data!
Nick recently blogged about a new web part available for users of his BDC Meta Man tool that allows users to use BDC data to generate a map via Virtual Earth. Cool stuff, but it's $300 if you want to buy it.
Did you know that it's really quite simple to include dynamic Virtual Earth maps to information stored in any kind of source in your site's Data Source Catalog (by the way, that includes BDC sources!) by using a Data View Web Part in SharePoint Designer? Greg Chan, one of the Program Managers on the MS SharePoint Designer team, blogged about this back in June, and included a step-by-step walkthrough. It's a great example of just how powerful SharePoint Designer is!
Check out the post here, it's definitely a keeper!
(Note: The SPD blog post doesn't show how to add a pop-up with arbitrary info in it. The Virtual Earth SDK, however, has some great info on how to do this. Maybe I'll blog about adding that feature, what do you think?
