Learn how to create a geometric buffer: the most commonly used tool within the proximity analysis class of spatial analysis.

In this tutorial I’ll show you how to use QGIS 3 to create BUFFER around your shapes and geometry.

Learn how to set distance, use the correct reference system (CRS) and to know the difference between linear, punctual and polygonal buffers.


A buffer in geographic information system is a zone around a geographic feature containing locations that are within a specified distance of the feature. A buffer is likely the most commonly used tool within the proximity analysis class of spatial analysis methods.
