4Pan and Zoom the Web Map

Use the mouse scroll to zoom in on your alignment, click and drag to pan around your alignment and alignment grid.

5Click Inside the Alignment Grid

In the OpenLayers map, click inside the alignment grid to get the station, offset and coordinates of the location you clicked.

6Save the Point You Clicked

Click Save Point to save the point information (station, offset, coordinates, alignment). Navigate to Points to see a list of all your points.

7Click To View Your Point

In the Points list, click the eye icon (on the right, under actions) to view your point again along with the associated alignment.
