Quite correct. Made an error. Carryover from a prior job where we mucked with weather data... I was thinking more along the lines of raster geo datasets like sat images, etc. Each pixel represents one geo location, with a carrying load of metadata, then a timeseries of that snapshot & md, so timeseries-raster-geomapped data basically.

I don't remember anymore what that general kind of datatype is called, sadly.
