Achtung.PNGNote: This fuction is still a BETA version and will be developped further. Your feedbacks are very welcome.

This function is available in course setting projects for sprint orienteering maps according to ISSOM 2007 / ISSprOM 2019.
It helps you to see and evaluate possible routechoises between two controls.
You will also get the shortest route for each course.

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

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.

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.

Define the perimeter

  • Entire Map: This may take quite long time to prepare the map, depending on its size.
  • Define perimeter: Draw a perimeter on the map. The perimeter will be shown with a light blue line. Routes will only be analyzed in this perimeter.

Draw leg and analyze route

You can calculate routes only between two points.

  1. Click on Draw leg and analyze route.
  2. Click and drag a line in the OCAD window.
  3. Repeat these two steps for further routes.

The routes will be saved in the Route Box.

Analyze routes (current course)

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

All routes will be saved in the Route Box.

Analyze routes (all courses)

  1. Click on Calculate routes (all courses).
  2. All routes for all courses will be calculated and will be saved in the Route Box.

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), which can be seen in the function Show Impassable 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.
You see on the left side, if the route is visible or not. The right side shows you between 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. The length will not yet be adjusted automatically.

Shift + Ctrl + Icon SelectObjectAndEditVertex.PNG Add Vertex
Ctrl + Icon SelectObjectAndEditVertex.PNG Remove Vertex
Ctrl + Icon RemoveVertex.PNG + 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

Achtung.PNG 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.
