Geographic information system mapping is designed to capture, store, manage and analyze spatial or geographical data. Information obtained from such systems is often used to create different maps representing given regions.
GIS maps can be used to show an estimated number of people living in a given region. Because these maps are created after careful considerations of various data, the results are usually quite accurate. These maps can be quite specific and show the number of individuals in a region according to profession. Users can actually tell the number of doctors, lawyers or policemen in a region by simply going through a GIS map, notes NationalGeographic.com.
GIS maps are capable of giving users a rough idea of each region on the map and what it is prone to. For example, a map can depict flood-prone regions against the landmarks situated close by. Researchers use these maps to analyze the characteristics of a given region over a period. This help in developing strategies to combat issues such as crime, flooding and any other form of disaster.
In most cases, GIS maps are developed with three-dimensional technology in order to give users a better picture of what is happening in a region. Updating such maps does not cost much and does not take a long time.
