QGIS Algorithm provided by QGIS (native c++) Small gaps (native:checkgeometrygap). Detects gaps between polygons smaller than a given area. This algorithm checks the gaps between polygons. Gaps with an area smaller than the gap threshold are errors. If an allowed gaps layer is given, the gaps contained in polygons from this layer will be ignored. An optional buffer can be applied to the allowed gaps. The neighbors output layer is needed for the fix geometry (gaps) algorithm. It is a 1-N relational table for correspondance between a gap and the unique id of its neighbor features.
