Option Analysis mode gives you more tools to understand route options better: the vertical profile chart, the composition chart, and the comparison chart.

First, select which option you would like to view in these formats by selecting them in the Option Selection Tile on the right-hand side. The selected option will have the word 'ACTIVE' displayed next to it in red.

The 'Show Components' option is located in the top-right corner of the Option Analysis window. Turning this option off hides the icons that symbolise crossing locations.

Vertical Profile Chart

The vertical profile chart plots chainage (length of route) against elevation, see the below figure. In this example, the river crossings are displayed against chainage and elevation.

To hone in on a particular section of the option, the chainage can be specified by "trimming" the total length of the route under the vertical profile chart to the desired section.

Composition Chart

The composition chart provides per-point quantities that show what occurs at every point along a route, including the constraints it encounters, topography information and the construction method required. In the example below, the aggregated penalty for all layers at each point along the option is displayed against chainage.

Along the x-axis of the chart, route icons (indicating crossings and towers) are displayed. These can be toggled off using the 'Show Components' tick box.

🗂Composition Chart Catagories

  1. Angle change - describes the change of angle at each route point

  2. Asset - indicates the asset at each route point, for example, Wood Pole, Steel Tower, Trenched Cable or Trenchless Pipeline

  3. Constraint - constraints broken along the route (only shown if there are any constraint breaks)

  4. Cost - the cost acquired from layers and crossings at each route point

  5. Crossings - linear feature crossings at each route point. The magnitude of the bar indicates the crossing angle.

  6. Height - the height of towers (available for overhead assets only)

  7. Layer - crossings of polygon layers

  8. Objectives[...] - the quantities contributing to objectives, for example, Objectivescapex

  9. Penalty - the total penalty at each route point from layers, linear features and slope/elevation ranges

  10. Slope - slope at the given route point

Comparison Chart

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.
