ABSTRACT
Throughout this chapter we will revisit the data from the Integrated Air Quality system of the Madrid City Council (section 10.1) to illustrate visualization methods applicable for point space-time data. This dataset comprises the time series of measurements acquired at each station of the network during 2011. In the section 8.1 the data were converted from spatiotemporal data to spatial data, where the time information was suppressed to display only the yearly average values. In this chapter we will work with the whole space-time dataset using the tools provided by the spacetime package (E. Pebesma 2012).
