At present, the use of information over networks generates multiple advantages at both a public administration (regionalisation, planning, networks, regional and urban development, etc.) and commercial level. In order for this use to be effective and adaptable, software supply companies developed what are known as GIS.
A Geographic Information System (GIS) basically links spatial elements shown on a map (streets, blocks, communication networks, municipalities, etc.) with information relating to them. This allows for the: STORAGE, EXTRACTION and ANALYSIS of data relating to one of the spatial elements.
GIS, however, does not only identify and gather information about an element through a simple mouse click but (and more importantly) plots the data in graphics, comparing and selecting elements based on certain characteristics, connecting an element to another database, etc.
This enables your company to quickly discover which agency makes the largest sales volume per month, what specific product stock is available in a certain city, show new elements (businesses, service stations, wells, etc.) through coordinates or postal addresses, enter census data in your area of interest to locate areas with the largest quantity of potential clients, obtain representative visual data of farming stocks at your properties, locate your most frequent clients in order to offer them a better service, etc.
A particular advantage that should be pointed out is that this geographical database is not static but rather dynamic as it can always be updated and improved.
