With OALLEY you can very easily create isochrones and isodistances areas for free. In some cases, it may be useful to define your zones manually, to adjust overlapping zones or to adapt to specific constraints you need to take into account.
To draw a zone manually, go to the map.
Once you’re on the map, go to the new area creation panel on the upper left to draw your first manual zone:
Select the “Handmade zone” mode by clicking on the corresponding button:
Then, define the starting point of your zone:
And click on “Draw” to start drawiog your zone.
Click on the map to define the points which will demarcate your zone.
To finish, click on the first point you have defined. You’ve just drawn your first manual zone!
