New approach to satellite imagery analysis

Geoscience Australia has just released a short 3 min. video presenting a concept of “data cube” for storing and analysing Earth observation imagery acquired by satellites. This proof of concept application has been built to work with Landsat data and was already used in an operational capacity on several data analysis projects. This is the future of analysis of big volumes of temporal, remotely sensed data.

The concept can be extended to work with any data that can be referenced to a grid structure (in fact, to any spatial data that comprise of a collection of points in space). This is not the first attempt to work with cubed spatial data but certainly the first that I know of that is capable of processing terabytes of spatial imagery into a variety of derived information for immediate, practical use.
