A common question we get is, “What is the resolution or scale at a particular zoom level in Virtual Earth or Windows Live Local?”  Well, that is actually a little more complex of answer than you might expect.  We use Mercator projection across the maps in the Virtual Earth Map Control so they can be be cut up into image tiles for quick delivery to clients and reliable stitching back together…

When instantiating the Map Control, you have the option to specify a starting coordinate set and zoom level for road or aerial view. But, you might be scratching your head on exactly what zoom level to start at if you want to get a particular level of detail.  I find the quickest way to find a good zoom level is to fire up Windows Live Local and get the view…

As many of you have pointed out to me, the v2 control does not support firefox as well as the Windows Live Local site does.  There is actually a wedge you can put in place to fix most of these issues, but it is not officially part of the SDK today. To use the wedge, add the following line to your html as the first line in the body element: <![if !IE]><script src=”http://local.live.com/JS/AtlasCompat.js”></script><![endif]> …

When we transitioned to Windows Live Local we implemented new servers for the tiles for vector, ortho, and other imagery sources.  This new setup is more scalable and better acommodates the kinds of traffic we need to handle for our own site and for our commercial customers and mashup builders.  Until now, we have kept the old tile servers running to keep our v1 mashups running.  But, alas, the time is approaching…

We Broke It!? A VE Map Search Control v1 Required Update

Share

Our recent change of the consumer site to Windows Live Local broke some of the functionality of the Map Search Control, or Commercial Control.  Apparently when we updated the site’s URL the redirect to the new URL didn’t work for the proxy we wrote, an error that didn’t surface in our testing. So, your Commercial Control application probably needs updating.  The change is simple but necessary–you must manually update the…
