Spatial Data Import and Exportbetween . objects in .and external formats, including the ones typically used by GIS. In this chapter, we first show how coordinate reference systems can be handled portably for import and export, going on to transfer vector and raster data, and finally consider ways of linking .and GIS more closely

Further Methods for Handling Spatial Data.. We first consider the question of the spatial support of observations, going on to cover the handling and combination of features using in particular the . package. Next we consider map overlay, also known as spatial join operations, including aggregation, extract operations in the . package, and

Spatio-Temporal Datan into account explicitly, because they are not relevant. In other cases, they are. Most of this book addresses the case where spatial location matters, and temporal variation is not present or ignored. Texts on time series analysis mostly do the reverse. This chapter will address first steps in han

The pattern of observation . is usually not of primary interest, as it often results from considerations ranging from economical and physical constraints to being ‘representative’ or random sampling varieties.

Modelling Areal Dataudy, may be arbitrary in others and may be administrative boundaries created for very different purposes in others again. The observed data are frequently aggregations within the boundaries, such as population counts. The areal entities may themselves constitute the units of observation, for example

Disease Mappingpatial variation of the incidence of a disease can help us to detect areas where the disease is particularly prevalent, which may lead to the detection of previously unknown risk factors. As a result of the growing interest, Spatial Epidemiology (Elliott etal.,2000) has been established as a new mul

Other problems include monitoring network optimisation: where should new observations be located or which observation locations should be removed such that the operational value of the monitoring network is maximised.
