Route Analyzer

This function is available in Course Setting Projects for Sprint Orienteering maps according ISSOM 2007 / ISSprOM 2019.
It helps you to see and evaluate possible routechoises between two controls.
You will get automatically the shortest route for each course.

--> See a short video on Youtube, which explains you the basics.

Open Route Analyzer

When you are in a Course Setting project, you will see a purple bar at the right side called Route Analyzer. Click on it and the bar will open.

How it works

When you run the Route Analyzer the first time, the function will need some time to proceed all necessary steps to show possible routes.
This includes:

• Process impassible features
• Create graph nodes
• Connect nodes
• Calculate routes

The larger your map is, the more time it will take to prepare the map. The calculation of the route itself will be quite fast. When you calculate new routes, it will be much faster, as the function doesn't need to prepare the map again.
Here, too, the longer and more complex the route is, the longer it takes to calculate.

The shortest option is displayed with a solid green line. The distance of the route is also shown with a text symbol.
Alternative routes are shown in red color. Routes counts as an altrenatives, if the are not more than xx% longer than the fastest route.

Route Analyzer Box

You can either calculate only a route between two points, the whole route of a course or the routes for all courses at once.
There are many ways to display the routes

Calculate routes (selected objects)

You can calculate routes only between two points.

1. Select two control or draw a line between two points. When you use a line, be sure to delete it again before printing/exporting the course.
2. Click on Calculate routes (selected objects).

The route will be saved in the Route Box.

Calculate routes (current course)

1. Select a course in the Course Box.
2. Click on Calculate routes (current course).

All routes will be saved in the Route Box.

Calculate routes (all courses)

1. Click on Calculate routes (all courses).

All routes for all courses will be calculated will be saved in the Route Box. This may take a moment, depending on how many courses you have. You can follow the progress in the lower left corner of the OCAD window.

Reset routing graph

Click on Reset routing graph to process again all impassible features and build up the nodes.
This may be necessary, if you detect a mistake in your map (e.g. an unwanted gap between two impassible features). After you corrected the mistake in your [Map File], you need to reset the routing graph, before calculating new routes.

Route Box

All calculated routes will be shown in the Route Box.
The left side will tell you, if the route is visible or not. The right side shows you betwenn which two controls the route has been calculated.

Show current course routes

Shows the routes of the select course in the Course Box. All routes of this course will be visible in the Route Box, all other routes will be hidden.

Show all routes

Show all routes in the Route Box.

Hide all routes

Hide all routes in the Route Box.

Delete all routes

Delete all routes in the Route Box.

Limits of the function

The Route Analyzer is a great function. However, it's not working in every situation.
These are the limits of the function:

• The function is not (yet) considering the runnability. It only distinguish between passable and impassable features. The fastest route may go through a green area.
  

  Positive side effect: You may notice routes that you have not thought off before (e.g. possible route through green area).

• The function can't deal with different running levels, e.g. underpass, overpass, bridges or tunnels.
  

Editing the routes

You can edit the routes manually. Just click on the routes and edit them.

Shift + Ctrl +	Add Vertex
Ctrl +	Remove Vertex
Ctrl + + Mouse	Remove Vertex with Mouse Over.

See the Tips with Keyboard and Mouse page or the Select Object and Edit Vertex page for more information.

Last but not least

Before printing/exporting your courses, be sure that all the calculated routes are hidden or deleted.
You probably don't want to give a map to the runners with all measured routes on it.
