Although one could argue that all data are spatio-temporal, as they
must have been taken somewhere and at some point in time, in
many cases the spatial locations or times of observation are not
registered, and irrelevant to the purpose of the study. Here,
we will address the cases where both location
of observation are registered, and relevant for the analysis of
the data. The
task views shed light on spatial, and temporal data handling and
In long tables:
In some cases, spatio-temporal data can be held in tables

time as three of the columns, or an identifier for a location
or region and time as columns. For instance, data sets in
for linear panel models have repeated
observations for observational units, where these units often
refer to spatial areas (countries, states) by an index. This index
(a name, or number) can be matched to the spatial coordinates
(polygons) of the corresponding area, an example of this is given

data sets usually contain more than one attribute, to hold the
data in a two-dimensional table a

unit, observation time, and all attributes.

When a single attribute is considered, another layout is that
