I am reflecting on a data structure that will allow us to perform all kinds of spectral operations we normally do in remote sensing. Due to lack of an appropriate data structure supporting spatially based spectral data, right now we have to keep our data in non-georeferenced N-dimensional arrays.

I have recently been introduced to the promising package called spacetime which helps solve some of the data management problems we regularly encounter with time-series of spatial data. I would like to congratulate the developers of this wonderful package. My question : Is there a way to
