units used by Driving Distance
Hello,
the in:parameter 'distance' unit used is degrees, why ? (cf. HTML doc "distance: float8 value of distance in degrees") Is this because the SRS of the graph geometry has to be EPSG4326/WGS84?
What about the unit of the 'cost' parameter? Is there a required unit / or can we used meters, km, miles, or even a time unit as long this is consistent with the content of the cost column?
Thank you. Best regards, patrick Gendre CETE Med, Aix-en-Provence, France
