Geographical Information Systems, A Tool In Public Health.

The development of Geographical Information System (GIS) as an assessment and evaluation tool and as a visual aid has enabled researchers to analyze different types of data sets through spatial analysis. In the last few years, the use of maps to analyze geographic information has been facilitated by different software companies. It is generally used in diverse known disciplines such as geography, social sciences, cartography, computer science and increasingly in different areas of Public Health (health assessment, disease surveillance, environmental risk assessment, etc). The application uses geographically referenced data as well as non-spatial data for map compilation. Through spatial analysis, it creates models by combining resource data sets. These models can be utilized in decision-making scenarios such as: identifying the best location for an underground storage tank, finding which sector of the population may be at potential risk of being exposed to high concentrations of a particular chemical, or mapping the spatial distribution of women of child bearing age in highly-populated areas. This technology allows us to integrate multi-source data into a manageable system and to obtain maps which help determine outcomes in the public health field at local, state or national level.
