This chapter discusses a wider range of epidemiologists to have access to the global environmental data (satellite and demographic) and demonstrates that remote sensing (RS) and geographical information systems (GIS) do not simply create pretty maps, but biologically informative information and ultimately pragmatic control tools. The chapter reviews current research topics that have emerged from the ability to consider epidemiological phenomena at the global scale and attempts to map the environmental limits of dengue and yellow fever at the global scale. It continues efforts to map the geo-helminths for the targeting of control activities. Tick-borne diseases are used as an example of how to coincidentally map geographic and phylogenetic space. The chapter also discusses methods and evidence required to evaluate the impacts of climate change on vector-borne disease.
