A :guilabel:`Only selected features` checkbox can be used to restrict the checking to the geometries of the selected features. 37. This algorithm finds duplicated geometries and removes them. One of: 0 --- Polygon. This doesn't work in QGIS because it requires an overlaying layer. You can create a virtual layer where you join the layer to itself based on a distance between two points. void That does not work. check (with default parameters) both tests report no errors for both layers, but QGIS Intersection reports invalid geometry for one or more input features. 10, QgsGeometry acts as a generic container for geometry objects.

Both can be used to find/delete features that have identical attributes, or, if the Shape field is specified, identical geometries. fid <> b. states a, us_counties. Decreasing the densifyFraction parameter will make the distance returned approach the true Fréchet distance for the geometries. states b where a. Once you have all valid geometries, you will notice that the performance of the Geometry Checker plugin, as well as many other The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. In water utility management, the Duplicate Feature check can be used to identify service points, system valves, and hydrants that contain stacked points in the same The problem is generated with invalid geometries, which is not exactly what the geometry checker plugin is analyzing. P. You can still try if it happens to work qgis_resource_sharing 1. Follow answered Jun 7, 2018 at This is similar to the way you'd find duplicates in an attribute, you need to join the layer to itself and then exclude self overlaps. regrarians.
