Why Use GIS? Any organization has new and legacy data stored in a variety of formats in many locations. It needs a way to integrate data so that it can analyze it as a whole and leverage it to make critical business and planning decisions. GIS can integrate and relate any data with a spatial component, regardless of the source of the data.
For example, one can combine the location of mobile workers, located in real-time by GPS devices, in relation to customers' homes, located by address and derived from one’s customer database. GIS maps this data, giving dispatchers a visual tool to plan the best routes for mobile staff or send the closest worker to a customer. This saves tremendous time and money. GIS can be applied to many aspects of business viz. facilities management, logistics, inventory control, target marketing, market analysis, and site location.
