The term Geographic Information Systems (GIS) is a term used to refer to a system installed in a computer capable of manipulating, assembling, displaying and storing information that has been geographically referenced. Large volumes of data are mapped, analyzed and modeled using a single database depending on their locations. In short, the software gives one power to create maps. Information such latitudes, longitudes, elevations and ZIP codes are fed into the system and the results can be used to determine whether and climate patterns of different regions (Global Geographic Information Systems, 2007). Different organizations use GIS generated data to seek information regarding specific areas of interest they are interested in.…show more content…
For instance, marketers may use the tool to map demographic information by displaying and analyzing data. The system is often used for market analysis tool and it is best beneficial to companies and organizations that cover a large geographical area and have many workers. GIS is used for general statistical analyses and its geo-coding component is also an important aspect. The GIS is designed to improve application for all users and its reliability is an attractive component. Establishing a GIS Model As attractive as the benefits of GIS may look to an organization, there are a variety of factors that need to be considered before this is done. Before the system is made, the number of users, GIS data base and application should be considered. The other key factor that comes in handy is the size of the geographical area. To add on this, the degree and frequency of use for each system also varies with its integration into the system. Before setting up a GIS system, one has to consider its functionality. If a system can run efficiently and effectively without this system, then it might be of no use incorporating this system (Somers 1998). The other point to note is the complexity of the GIS in use. The more complex a system is the more resources it handles at a time. Complex structures are often associated with complex and large organizations that require a lot of data feeding and have a lot of resources. For one to ascertain how they want their system to
