open-in-new
<p>In <a href="/facts/Geographic_information_system/PoP1kVoa">geographic information systems</a> (GIS) and <a href="/facts/Spatial_analysis/R6rlDzRl">spatial analysis</a>, buffer analysis is the determination of a <a href="/facts/Locus_(mathematics)/t4swdGJq">zone</a> around a <a href="/facts/Geographic_feature/MRbCqBmW">geographic feature</a> containing locations that are within a specified distance of that feature, the buffer zone (or just buffer). A buffer is likely the most commonly used tool within the <a href="/facts/Proximity_analysis/lp4ny7z0">proximity analysis</a> methods. </p>
