Buffer Analysis
The process of creating and analysing buffer zones to assess spatial relationships and impacts, such as identifying features within a certain distance of a point or line.
What does Buffer Analysis mean?
A geographical analysis method called buffer analysis is used in GIS to locate and investigate regions that are within a given radius of a geographic feature, like a point, line, or polygon. It entails establishing buffers, or zones surrounding features, and determining what is inside and outside of those zones.
For example:
Buffer analysis can be used in environmental planning to identify sites that may need protection if they are 500 meters or less from a river.
It can be used in urban planning to pinpoint buildings that are close to a road or utility line.
For proximity-based decision-making, such as resource management, emergency preparation, impact assessment, and site selection, buffer analysis is frequently utilized. It aids users in comprehending the interactions and spatial relationships among various features within a given geographic area.

By establishing zones around features at a predetermined distance, buffer analysis in GIS aids in proximity analysis and supports planning, environmental, and transportation decisions.
In GIS, spatial buffering is a method for establishing zones at a predetermined distance around geographic elements, such as points, lines, or polygons. These buffer zones are crucial for tasks like risk assessment, urban development, and environmental planning since they aid in the analysis of proximity, influence areas, or prospective impact.
Planning, safety, and resource management are aided by buffer zone analysis, which in GIS establishes zones around features at a predetermined distance to examine proximity and impacts.
In GIS, buffer analysis establishes zones around features to examine their proximity. Among the different types are nested buffers (overlapping zones), variable-distance buffers (depending on attributes), multiple-ring buffers (concentric zones), and basic buffers (uniform distance). They support risk assessment, environmental investigations, and planning.
