Buffer

Buffer analysis is a fundamental spatial analysis technique widely used in Geographic Information Systems (GIS) to support planning, management, and decision-making processes across various sectors. It involves creating buffer zones at specified distances around geographic features such as roads, rivers, buildings, utilities, or administrative boundaries. These zones help identify areas of influence, accessibility, proximity, and potential impact. In environmental management, buffer analysis is used to assess ecological protection zones, evaluate the effects of human activities on natural resources, and support conservation planning. In urban and regional planning, it assists in determining service coverage areas, identifying suitable locations for infrastructure development, and analyzing land-use patterns. Transportation studies utilize buffer zones to evaluate accessibility to roads, transit networks, and public facilities, enabling better mobility planning. Additionally, buffer analysis supports resource allocation by identifying populations or assets within a defined distance from critical services. By revealing spatial relationships and areas affected by specific features, buffer analysis provides valuable insights that enhance geographic understanding, improve planning efficiency, and support evidence-based decision-making.
