Показать описание
Buffering is a common tool in GIS. It is a neighborhood function of spatial analysis which uses geometric distance to define the area of certain distance extent within target locations.
It's one common application could be for a road expansion project.
In this tutorial I'll be showing you how can you do it in QGIS by using a road vector data.

nice video, thx
an alternative quick & dirty method is to use, from the buildings layer, the "select by expression" with : overlay_nearest( 'road', max_distance:=10)
to reflect more what you did creating a buffer you could use the "select by expression" with:
intersects(buffer(geometry(get_feature('road', 'fid', 1)), 50), $geometry)
the geometry road has an attribute 'fid' with 1 as value, 50 is the width of the buffer in this case
