Geo describes an immersive hotdog as:
a georeferenced linear collection of immersive photographs which create a seamless immersive environment which can be entered in a Geospatial Exploration System such as Google Earth, Microsoft Virtual Earth, ESRI ArcGIS Explorer, or NASA’s WorldWind. The shape of these immersive collections roughly resembles a hotdog.
Moving from a series of panoramic images to a seamlessly stitched scene is the ultimate aim, we recommend reading Geosquans full post on his blog and then having a think about it…
Its an interesting concept.
