ArcGIS Runtime calculation precision ?

JeremieJoalland1 — Fri, 05 Sep 2014 10:09:28 GMT

I'm developing an application in ArcGIS Runtime for Java 10.2.3 with basic tools like :

- showing mouse cursor coordinates,

- calculated distances, areas (geodesic with GeometryEngine).

How can I have the precision of these calculations to provide them to the end user ??

(most of my maps will be in WGS 84, but precision will differ depending of map projection, right ?)

Hi Jeremie,

I've almost answered this a couple of times, but I guess I just need to clarify what you are trying to do.

The way I'm interpreting this is that if you are looking at a map at say a scale of 1:1 Million and you click on the map to digitize a point (which may be used to calculate a distance or draw a line etc) that point will be recorded to a given precision... is that what you are trying to display?
