GIS

Definition

GIS, or Geographic Information Systems, is a framework for gathering, managing, and analyzing spatial and geographic data. It enables users to visualize, interpret, and understand data through maps and 3D scenes, making it essential for tasks like planning and decision-making. In the context of network analysis and routing applications, GIS plays a critical role by providing tools that help model transportation networks, optimize routes, and analyze the accessibility of different locations.
