Map editing help

Map editing consists of several steps listed below.

To add an object of the desired type, click on the button on the right panel.

Step 1: Setting the obstacles

Obstacles on the map can be passable and impassable. Passable obstacles are marked by a dashed contour.

Types of obstacles:

  • Trees and other vegetation. Shown in green. People do not like scrambling through bushes, but in principle they can do it if needed.

  • Water barriers - rivers, ponds. Impassable for pedestrians, marked in blue.

  • Buildings and other structures. Impassable for pedestrians, marked with dark gray.

  • Roads, the carriageway without the sidewalks. Pedestrians will avoid them, but they can cross them.

  • Other obstacles. Any impassable obstacle not covered by the above categories.

Step 2: Paths

Step 2: Paths

Step 3: Attraction points

Attraction points are the points on the map between which pedestrians move. These can be house entrances, transport stops or just a playground with benches. All paths leading beyond the considered simulation area are also marked as generators.

They are added to the map using a tool

Step 4: Map border definition

Sometimes it happens that because of absence of obstacles surrounding the area in question, pedestrians begin to find new routes and flow out of the zone being considered. To avoid this, you can manually specify the boundaries of the simulation zone using the "border tool".

Submitting your map and receiving the results

You can download the map in GeoJSON format using the button

When editing is complete, press the green button to submit the map to the server. You will receive its unique ID. Enter this ID in the form at the top to check the status of the map.

The status of the compute server and the number of queued maps can be checked

After you finish working on this page you can see the result. Red marks denote the places where, according to the algorithm's prediction, pedestrians will walk across the lawn.

The algorithm correctly identified the main problem of the site - the trails through a wide lawn. Particular outlines and exact location may differ from reality due to inaccuracy of the map and accidental motion of pedestrians. However, this result is enough to determine the areas that need improvement.

You can download the result using the buttons at the bottom (image + json description of the map in an archive) or return to map editing.
