 <h3>Topology cleaning</h3>
 
-When importing polygons, non-topological polygons are converted to
-topological areas. By default, a very small snapping threshold is applied
-(1e-13 map units) to avoid topological errors caused by numerical inaccuracy
-of the input data format. If the original polygons contain errors (unexpected
-overlapping areas or small gaps between polygons), the import might
-need to be repeated using a larger <em>snap</em> value.
