Option comparison is used to help with deciding which corridors or centrelines are best based on selectable parameters. There are two ways of visualising the metrics:

  1. Spider Chart

    The spider chart is an effective way of understanding ways in which routes differ.

  2. Comparison Table

    The table allows you to view specific parameters for each selected option.

Setting up your Spider Chart and Table

  1. Go to the Analyze Window and select the Option Comparison icon on the left-hand toolbar, shown in the diagram below.

  2. Select the Options you are comparing.

  3. The Option Comparison Tile on the right has a search bar. This is where you will select the parameters you wish to compare. If you click on the search bar the parameters appear in a list as you click on them, they will be added to the spider chart and table.

The parameters available will be dependent on the configuration used. There are a lot of parameter names and knowing them comes with time. Here are a few tips so that you can find what you need,

  • The route length can be found at the top of the list or can be searched for under 'Total Length'.

  • For information specific to a data layer, search that data layer name. There will be options for;

    • Distance to nearest features of that data layer.

    • Length of that route going through that data layer.

    • Number of features of that data layer that are within a specified buffer.

    • Number of crossings - for data layers showing linear features such as rivers, roads or utilities.

  • To find anything relating to features around a centreline search for 'catchment' and select the parameters that relate to the catchment distance and data layer you are interested in.

To export the Spider Chart and table, go to 'Onboarding 5 Exporting Results'
