How GIS benefits businesses and other fields
GIS allows visualization of land areas in new ways. With the help of GIS, it is possible to map the exact location of objects, as well as scout for locations which may have inputs or resources. The technology helps to quantify requirements and scout for places where resources of given quantities are located and use them to the benefit of organizations.
An example would be in the garment industry, where business owners would be interested in finding out conurbation areas where families using the types of attire that are manufactured by the company, and filter income data to find high income groups. This would make it easier to locate stores and sell products.
Healthcare organizations would want to know the number of doctors available per 1000 people in a particular area, so as to be able to make informed decisions for placement of doctors. In developing nations in particular where medication can be in limited supply, GIS is an important tool that is used to identify areas served by medical communities and those which are not served adequately.
GIS density maps enable determining the distribution patterns prevailing in defined areas for particular products and services. The technology has already been of use to properly map counties or census tracts which may vary in population density. In situations where it may not be necessary to have a higher number of people on larger tracts of land.
Law enforcement departments, for example, needing to find the concentration of drug trafficking areas to determine whether such activity has been found within a kilometer radius of schools or public utility buildings. It can help in detecting what is happening in adjacent areas as well. When combined with past data, such systems can help in mapping changes so that the impact of particular actions can be evaluated.
