Is there any plan to make the isochronen API work the opposite way ? Means a question like “give me all points from which I can reach a point in 10 minutes” ? Sometimes it will give very different results as the current API with a start point. I have some cases here with a lot of one-ways where the resulting polygons are very different. I tested it with ESRI which has the option To- or FromPoint.

Hi @Freudi,

You are right, these are two different calculations. A standard isochrone follows the roads from the start point towards the exterior. Your question is the opposite direction: the roads that arrive at the end point. When there are many one-way streets, the two polygons can be very different.

For the moment, the Woosmap isochrone supports only the first direction. The endpoint accepts one `origin` and there is no parameter to invert the direction. So it is not possible today.

I have transmitted your request to the routing team. I cannot give you a date at this stage, but the need is noted.

If you need a solution before we support this natively, there is an approximation with the [Distance Matrix](https://developers.woosmap.com/products/distance-api/features/matrix/): create a set of points around your target, send them as `origins` with the target as the only `destination`, and keep the points under your time limit. It is not precise and it consumes many requests, so it is more adapted to an analysis than to a live feature. Tell me if it is useful and I will send you the details.

Best regards
