Name the system used for geographic information systems (GIS).

The system used for geographic information systems (GIS) is accurately identified as spatial data analysis and mapping technology. GIS integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. The core function of GIS technology is to visualize spatial relationships and patterns through mapping, which enables users to analyze geographic data effectively.

This technology encompasses various functions, including data collection, data management, and analysis—facilitating the creation and use of spatial datasets. It is utilized in a variety of fields, such as urban planning, environmental science, and resource management, making it a crucial tool for decision-making that relies on geographical contexts.

While remote sensing technology involves collecting data about the Earth from satellites or aircraft and can complement GIS by providing additional geographic information, it is not the primary system used for GIS. Similarly, statistical analysis software is aimed more at analyzing numerical data rather than managing geographic datasets. Physical mapping techniques focus on traditional ways of creating maps without the advanced capabilities offered through GIS technology. Thus, the selection of spatial data analysis and mapping technology encapsulates the essence of what GIS represents in practice.
