Figure 1From: Land cover, land use and malaria in the Amazon: a systematic literature review of studies using remotely sensed dataLocalization of the study areas. Points, dotted and dashed circles and lines schematically represent, respectively, local (study areas lower than 6,000 sq km), regional (from 22,500 [27] to 225,116 sq km [14]) and large scale studies. Point size and line width are proportional to the number of studies. Circle sizes do not strictly correspond to the study area surface.
