GIS
GIS (Geographic Information System) is a framework for gathering, managing, analyzing, and visualizing spatial or geographic data. It integrates hardware, software, and data to capture, store, manipulate, and display geographically referenced information, enabling users to understand patterns, relationships, and trends in a spatial context. Common applications include mapping, urban planning, environmental monitoring, and logistics.
Developers should learn GIS when building applications that involve location-based services, spatial analysis, or mapping, such as in real estate, transportation, agriculture, or disaster response. It is essential for creating interactive maps, performing geospatial queries, and integrating with GPS or satellite data to solve problems related to geography and spatial relationships.
