Isochrone for small distances (pedestrian)


#1

Hi all,
I just discovered this tool, it is really great!
I’m wondering if there are some minimal distances to get an accurate map. I have been doing isochrone calculation in a zone with a canal and no bridge within 3 min walk and yet the accessible zone is going over the water. (see picture below).
isochrone_jumping%20the%20canal|690x353
I was trying to make a point that this zone is kind of an enclave for pedestrians due to the canal but the map doesn’t go in this direction.

Thanks for your tips :wink:

Best regards.

Hi @chloemis

Do you have another link to the image as that one doesn’t seem to work?

Hi Adam,
Here is the link to the map, better?

And here the image again

Yup, that loads now :slight_smile:

For shorter distances the isochrones are always a little off because of how the polygons are generated. But you are right that it shouldn’t go over into the other side of the canal. We will have a look into it to see if there is some way of making it more accurate.
