Option analysis gives you two more tools to understand route options better: the vertical profile chart and the composition chart.
First, select which route you would like to view in these formats by clicking on it in the Option Selection tile to the right-hand side. The selected option in the option selection list will say 'ACTIVE' in red font. From the first figure in this article, we can see that this is the first option on the list.
Vertical Profile Chart
The vertical profile chart plots chainage against elevation for the length of the route, see the top figure. In this example, the river crossings are displayed against chainage and elevation.
The chainage you wish to view can be selected by dragging the orange bars on the plot under the vertical profile chart to the correct position.
In the top left-hand corner, there is an option to 'Show Components'. By toggling this off the icons which symbolise the locations of crossings will no longer be visible.
The composition chart provides per-point quantities. It can display lots of information about what happens at each point including constraints, topography information and construction method required. In the example in the bottom figure, the constraints at each point are displayed against chainage.
The comparison chart plots the values of two per-point quantities along the length of the route. This can be used to identify 'trade-offs' or the location of routes that present risks relating to two constraint types.
