The second way to derive X and Y is to use the Field Calculator. Let's add a name field. Instead, go to ArcCatalog, right-click the table, and choose Create Feature Class from XY to create a new feature class from it. To check, sort by roadDist (click on the roadDist column header), select those with zero distance, and then see were they are on the map: they should be on a road. Opening an URL Action Let's start with creating a simple action to view a camera traffic when a camera point is clicked on QGIS map canvas. When an attribute table is set to a "Layer features" source, this new feature allows the underlying vector layer from which to source features to be data defined. So for roads, the layer we loaded in our basic map we will view its attributes. In the Menu, select View ‣ Identify Features. , symbolization, labeling), open the attribute tables, and so on. In the first three lines I created a uri which is the path to where my file is stored. Tables can be added to QGIS by simply dragging them down into the Layers. You can open an Excel file with the menu option or button 'Add new vector layer'. When we create our new layer, the attribute table will only have one column by default - id.
