Hi,

when I'm requesting the length by using the Geometry Service, the response is alway in miles.

In ArcGIS Server 10.1 it is possible to pass a unit. In ArcGIS Server 9.31 it is not possible. How could I configure this?

Cheers,
Bernd

I'm passing as SR 102100 (Web Mercator). Isn't is based on a metric coordinate system?

-Is your result in miles OK?
-Is your ags 9.3.1 patched?
-Do you try another wkid with units meter for see if you have result in meters.
