The document discusses how geographical information systems (GIS) and business intelligence (BI) are becoming increasingly integrated to form spatial intelligence (SI). It notes that GIS and BI have begun leveraging each other's strengths through technological advances that allow their integration without disrupting existing IT environments. This integration provides users with intelligent maps and spatial data mining capabilities through various architecture proposals that connect data warehouses, BI servers, GIS servers and features. The combination of GIS and BI is said to provide higher returns on investments by extracting more value from location data and existing assets.
