I have groups of vector points (GPS points) in a number of layers in QGIS. I would like to connect the points in each layer into polygons in each individual layer. I have look hard, but can not find away within QGIS to do this ?
You need the "points to path tool" from the processing menu, I think you mean lines not polygons?
If you want a polygon use the buffer tool from VECTOR/GEOPROCESSING TOOLS menu to create a buffer around your points.
