Streaming and Vector Maps

Im currently developing some experiments with modest maps, focusing on better user experience with maps since im UI designer.

One idea is improve the tile loading by showing the image before they have fully loaded passing the loaded byes using byteArray and fill the loader with data.
The result is a live streaming map like google earth. But since almost every mapprovider use non-progressive images tiles this don’t work very well. If we provide a custom map with progressive tile images works like a charm.

You can test this aproach by replacing the Loader class by StramLoader in LoadMovieThrottledRequest.

StramLoader class:

Another idea for vector maps is use MapServer with svg extension as the mapprovider of ModestMaps and render each tile using Degrafa with svg data, but this seems like a lot of customizing work.

Let me know what you think.
