At last, serving huge quantities of 3D geospatial data into interactive user applications is getting easier and more accessible. Support for ‘3D streaming’ is gaining a foothold within popular geospatial applications, paving the way for data providers to present their own 3D data assets in ways that users will find natural and accessible. For us at OS, this is a development that we’re very excited about, as we believe it will be a powerful tool in helping to unlock the potential of geospatial 3D data.
For many people, Google Earth (launched in 2005) was their first experience of navigating a ‘digital globe’ – a tool that is typically supported by ‘streaming’ technology. Overwhelming volumes of geospatial information were clearly available, yet how had it got there? Although Google Earth was then only available as a downloadable app, it was clear that the data was being sourced quite independently. For many of us, this served as our introduction to ‘3D streaming’ – the ability to selectively deliver content, based upon real-time navigation, within a 3D scene.
