Virtual planet learns to sing

Impressed by the video. I share thoughts.

1. The first geosystems learned to understand a flat geographic reference. Many jokes arose due to the fact that the Earth is round and the "paper" is flat.

2. Then they realized that in 3D you can add a third coordinate and additional dimensions related, for example, to the length of the path. At this, the geometry, in fact, at the heart and ended.
3. Then came the prototypes of virtual reality based on geographic data - Google Earth. These added time - now the combination of space-time reference is absolutely appropriate.
4. Now sound appears. In the space-time context. As a fact.

There are no tags in the base KML so far that are responsible for working directly with the spatially targeted nearest sound. This is a manual work of the authors as a demonstration of the idea.

It is obvious that the adaptation of existing services for the issuance of geotime (sound) tied content is a purely technical matter. The issue of tag standardization in the same KML is also a matter of time. Client services will also gradually catch up (including HTML5 and latest desktop delights). GE is the closest here, but the road is still empty.

Start given. Hope the sound will be heard.
