How geographic data warehouses create better analysis and decision support
Executive summary
Geographic information systems (GIS) are being used in an increasing number of organizations to analyze and visualize geographic data. By combining different data layers into maps, organizations can identify relationships, analyze risks, and inform decisions in complex business processes.
The foundation of all GIS analysis is map layers, also known as data layers. Each map layer represents a type of geographic information, such as property boundaries, buildings, elevation data or infrastructure.
When multiple data layers are combined in an analysis, organizations can get a more complete picture of how different geographic factors affect each other.
In this white paper we describe:
-
what map layers and data layers are
-
the types of data layers used in GIS analysis
-
how data layers are combined in analysis
-
how organizations use GIS analytics in practice.
