Dear stats experts,

it is very timely indeed to consider the strong overlap of statistics and
geospatial data, services, and applications.

Actually, the concept of multi-dimensional data analytics has first gained
traction in statistics with OLAP datacubes [1]. The same concept, however, also
plays a strong role in spatio-temporal geo data meantime. OGC, ISO, and INSPIRE
know the "coverage" concept for modelling and serving n-D coverages [2], with
proven specs and impementations, used , eg,for 1D timeseries, 2D imagery, 3D
x/y/t image timeseries and x/y/z geophysical voxel data, and 4D x/y/z/t climate
and ocean data. Therefore, it is an important topic to discuss coverages vs
statistics datacubes, exploring ways to bridge the gap and look at the avenues
which combined patio-temporal / statistical analytics opens up.

Given this, the Charter should explicitly mention this as a topic of
investigation referencing the relevant coverage standards [3],

- Coverage Implementation Schema (CIS) 1.1,

- Web Coverage Service (WCS) 2.1,

- Web Coverage Processing Service (WCPS) 1.0.

best regards,
Peter
