Gis (geographic information systems)

Definition

GIS, or Geographic Information Systems, is a technology used to collect, analyze, and visualize spatial and geographic data. It combines hardware, software, and data to manage, analyze, and display information related to geographical locations, making it a vital tool for understanding urban environments. GIS helps map out urban spaces, revealing patterns, relationships, and trends that might not be obvious through other methods.
