Spatial epidemiologySpatial epidemiology is a subfield of epidemiology focused on the study of the spatial distribution of health outcomes; it is closely related to health geography. Specifically, spatial epidemiology is concerned with the description and examination of disease and its geographic variations. This is done in consideration of “demographic, environmental, behavioral, socioeconomic, genetic, and infections risk factors." Disease Mapping Disease maps are visual representations of intricate geographic data that provide a quick overview of said information.
Digital mappingDigital mapping (also called digital or computer cartography) is the process by which a collection of spatial data is compiled and formatted into a virtual image on a computer. The primary function of this technology is to produce maps that give accurate representations of a particular area, detailing major road arteries and other points of interest. The technology also allows the calculation of distances from one place to another.
ArcGISArcGIS est une suite de logiciels d'information géographique (ou logiciels SIG) développés par la société américaine Esri (Environmental Systems Research Institute, Inc.). thumb|Exemple de carte réalisée avec ArcGIS Esri développe le système ArcGIS (auparavant appelé ArcView GIS). Ce système est composé de différentes plateformes qui permettent aux utilisateurs SIG, qu'ils soient bureautiques, web, ou mobiles, de collaborer et de partager l'information géographique. En 1999, Esri lance la version ArcGIS 8.
Map symbolA map symbol or cartographic symbol is a graphical device used to visually represent a real-world feature on a map, working in the same fashion as other forms of symbols. Map symbols may include point markers, lines, regions, continuous fields, or text; these can be designed visually in their shape, size, color, pattern, and other graphic variables to represent a variety of information about each phenomenon being represented.
