Which information system uses data visualization technology for planning and decision making in the form of digitized maps?

The accurate response to the question is the Geographic Information System (GIS). GIS employs data visualization technology to create digitized maps that help in spatial analysis, planning, and decision-making. It integrates various datasets related to geographical information and allows users to visualize complex data in a mapping format. This capability is essential for multiple applications such as urban planning, resource management, environmental monitoring, and disaster response, where understanding spatial relationships and geographical context is crucial.

The ability of GIS to present data visually makes it a powerful tool for decision-makers, enabling them to interpret data based on geographic locations effectively. This feature sets GIS apart from other information systems, which might not utilize spatial data visualization in the same impactful way.

The other information systems mentioned serve different purposes: a Decision Support System (DSS) focuses on assisting with decision-making through analysis of data but does not inherently utilize maps; a Management Information System (MIS) supports managerial decision-making through comprehensive reports and summaries of operational data; and a Transaction Processing System (TPS) is primarily concerned with the collection, storage, and retrieval of transaction-related data, lacking the analytical component that GIS offers.
