Mismatch between the center of the isochrone and requested location

Hi @timothy,

Thanks a lot for your quick answer. If I understand correctly the isochroning process of ORS, it works as follows:
(1) ORS locates the nearest point from the requested point that belongs to a road suited to the requested profile (driving, walking…)
(2) From this new point, ORS draws the isochrone

Is that correct ? In step 1, does ORS take into account the requested profile ?

And last question : which road network does ORS use to draw the isochrone ? At which frequency is the source network being updated ?

Thanks again,

M
