Health research based on geospatial tools: a timely approach in a changing environment.

摘要: The possibilities of disease prediction based on the environmental characteristics geographical areas and specific requirements causative infectious agents are reviewed and, in case parasites whose life cycles involve more than one host, needs intermediate hosts also referred to. information systems framework includes epidemiological data, visualization (in form maps), modelling exploratory analysis using spatial statistics. Examples include climate-based forecast systems, concept growing degree days, which now exist for several parasitic helminths such as fasciolosis, schistosomiasis, dirofilariasis malaria. paper discusses limits data collection by remote sensing terms resolution capabilities (spatial, temporal spectral) sensors on-board satellites. Although gained from observation oceans, land, elevations, land cover, use, surface temperatures, rainfall, etc. primarily weather forecasting, military commercial some this information, particularly that climate research satellites, is direct utility. Disease surveillance early-warning (EWS) prime examples academic approaches practical importance. However, even activities construction virtual globes, i.e. computer-based models Earth, have been used respect. Compared to conventional world maps, they do not only show man-made features, but can be spatially annotated with distribution, demography, economy other measures particular interest.
