The Geographic Information Systems (GIS) as part of applications for GeoMarketing have similar approaches to business intelligence. So much so that often appear in both areas in a single project. The discussion about whether or not geomarketing BI rate seems very productive, but instead are really interesting if the added value they can bring to business processes as well as the technologies involved. We have already commented on some occasions the spectacular results they were producing the integration of BI and GIS. A simple definition of GIS would be an information system that manages data with exact locations on a representation of the physical world, what we call spatial data and thematic attributes referring to referenced objects with spatial data. In a GIS capture, collect, store, analyze, share, manage and display geographically referenced information.When we have to build a GIS first thing we do is analyze the information to be integrated. Often we will find different formats (CAD, other digital formats, PDF, paper …). The objective of this analysis will standardize and unify this information, building a database type is called geographic database. After this we design a process that is almost always in BI projects: ETL. Within the BD geographic mapping information is integrated with information from other systems, as can be CRM, ERP, maps, design tools. From a technical point of view can be anything integrable: data warehouses, datamarts, databases, scanned images … In a geographical BD is modeling the real world in terms of objects with its graphic representation in terms of size and dimension on the surface of the earth.These data, which we call mapping, in turn are integrated with what is called thematic attributes. Typical examples of thematic attributes are sociological data, economic and demographic factors. The objects are organized in geographic information layers. Objects that have the same physical location are organized in different layers and can be viewed or not as required. For example, if a company wants to represent the physical location of their customers and prospects to make a marketing campaign, we would have in a GIS cartographic map of the city in question on one side and would represent such attributes available on such thematic purchases by existing customers and potential purchasing power. The analysis of this information may eg geographical areas delimiting interesting common denominators between potential and current customers.With this knowledge could create a localized campaign to lower cost and therefore very productive. This provides the GIS analytical capacity to handle georeferenced data bearing in mind that what interests us is that you are referencing objects with a spatial component on which information is associated. GIS is often classified into type vector or raster type but currently the information is handled with both. On the other hand there are the latest Object-Oriented GIS. Vector GIS using points and vectors defined in terms of pairs of coordinates and elevations relative to a mapping … Moreover Raster GIS are particularly suitable in those cases where the objects represent are diffuse or difficult to define such as an oil slick or a cloud.
