My Government Services: distance decreases when route calculated

Question

I understand that the initial distance shown in the carousel between the input point and "Library", for example, is based on a straight-line distance.  Then, when you click the icon to calculate the route, the "Total Distance" is calculated based on the actual route, and increases slightly.  In my case, the "Total Distance" is LESS THAN the original number, like maybe half or a third of it (could be meters to feet ratio?).  The mxd coordinate system is set to WGS 1984 Web Mercator (auxiliary sphere), so I don't know what else to change.  Our original data is in state plane, but that's the same as the Naperville example.  Any ideas?  Thanks,  Greg

BTW, only works on Firefox & Chrome -- which issue is in a different thread!

Aha! That makes sense -- my basemap is in State Plane.  Kind of a pain, but it does make sense...Thanks for taking the time to check this out.      Greg

I think the problem is that your basemap layer:
http://gis2.accessfayetteville.org:6080/arcgis/rest/services/BaseMaps/BaseMap/MapServer

is in this SR:
Spatial Reference: 102651  (3433)
or maybe it's that it's in feet.

If I recall correctly, the first basemap that's added sets the map SR.  Maybe you can just change your operational layers' mxds to be that same SR.

Don't know if this helps you but I looked in Fiddler and the out SR on the routeserver request is 102651 when it should be 102100 so you're right in thinking it is an SR problem.
