I'm working on a project that will involve both "raster data" (aerial imagery and DEMs) and "gridded data" which I understand to be other kinds of numerical measurements taken at grid points, and which could be completely non-image related (eg, population density).
I'm having trouble finding much on "gridded data", so I'm wondering if it's just a different term for raster data? Is there any fundamental distinction? Are there different tools (and particularly servers) for these two types?
(If relevant, this is in the context of Australian state governments...)
