Isochrones represents the area one could travel within a given time or distance
This formula supports 3 modes of transportation and the option to supply up to 4 contours for time or distance.
Using the denoise and generalize parameters will make for simpler polygons, this is especially useful if you want to limit features size for your datasets or other parameters. For example the static image formula will not run properly if the feature is too large (caused by character limits in Mapbox API).
