WebApr 4, 2024 · 27.2.8.1. Build virtual vector. Creates a virtual vector layer that contains a set of vector layers. The output virtual vector layer will not be opened in the current project. This algorithm is especially useful in case another algorithm needs multiple layers but accept only one vrt in which the layers are specified. WebGeometries can be simplified under the Simple Features model but, since each geometry is processed independently, the topological relationships between features can be disrupted. For instance, using the Simplify Geometries tool in QGIS, I can simplify the polygons dramatically but we see gaps between polygons and other side effects. twitch facebook connect
