The features are shown in the list by the name of the layer they belong to and the display expression. One potential problem I just noticed is that all fields in the attribute table of the original vector layer are exported to the kml layer as ExtendedData. zip file containing the state polygon, car theft point file, and QGIS Layer Style File is can be downloaded here: car-files. 0 User Guide 10. In this example, I am going to calculate the length of every feature in a contour layer. The attributes from both source layers are copied to the new feature:- To calculate the area of overlap, update the newly created feature's attribute table with its area. Users can change the viewing order of the layers, open the layer properties, and open the attribute table in this area. A new layer called Hub distance should now display lines to hubs, indicating the nearest bus stops to each polygon in the opt_1 layer. Each row in the table represents a feature (with or without geometry), and each column contains a particular piece of information about the feature. 16 it is now easy to create a new GeoPackage as it has been integrated into the Layer toolbar and Layer -> Create Layermenu.
