Map of Birds Eye Coverage in EMEA & APAC (Part 4)

Step 3: Are Bird's Eye Images Available?
In the next step I use a small .NET-application which I developed myself to retrieve the centroid of each of those tile-shapes:
SELECT BBox.STCentroid().STAsText() FROM [VE-Tiles] WHERE ID=24


The application will spool out a HTML-document and a JavaScript. Once I run this script the map will be positioned on each
point and execute the Virtual Earth method GetBirdseyeScene(). It will also update the database and set a flag for each tile where
we have Bird’s Eye images.


Step 4: Create the Tile-Set

My tiny application can do even more. It will generate colored tiles with a name (quadkey) and size (256 x 256) which matches those of the original VE-tiles. With some GDI-methods I will create the tiles for the lower zoom-levels. And that’s it. I have now my tile-set which I can overlay on top of Virtual Earth. Check out the mashup here.

    Thanks for the feedback. You are right. For some reason Venice was not in the SHP-file I got. Please keep reporting these issues and I will fix it with the next update.
