Isochrones, reverse isochrones, sensitivity analysis, and routing trees are all derived from gridded binary data, so we let the Grib Manager handle them. Open up the Grib Manager: you’ll see them appear under the heading “Internal”. Click on a light bulb to make them visible on the chart. (We didn’t make them visible by default because it can really clutter up the display.)
Note that you have to generate both isochrones and reverse isochrones to get the sensitivity analysis. These can be selected through the route options window.
