With OALLEY, you can draw isochrones and isodistances very easily and free of charge. In some cases, it may be useful to set out your areas manually, to adjust overlapping areas or to adapt to specific constraints that you need to take into account.
To draw a manual area, go to the map.
When you’re looking at the map, go to the area-creation panel at the top left of the screen to draw your first manual area:
Select “Manual area” mode by clicking on the corresponding button:
Next, set your area’s starting point:
And click on “Draw” to start drawing your area.
Click on the map to set your first point. Set as many points as you need in order to draw your area.
Click on “Undo” to erase your last point, click on “Leave” to stop drawing your area.
To finish your area, click back on the first point again. You’ve just drawn your first manual area!
