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

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.
- 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.
- Click on Draw leg and analyze route.
- Click and drag a line in the OCAD window.
- Repeat these two steps for further routes.
The routes will be saved in the Route Box.
Analyze routes (current course)
- Select a course in the Course Box.
- Click on Analyze routes (current course).
All routes will be saved in the Route Box.
Analyze routes (all courses)
- Click on Calculate routes (all courses).
- 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.
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.
- Further mistakes may also be a result of bad map drawing. Check the function Show Impassable Features.
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.
