Datum Transformation in Silverlight API 2.4

[prashantk]

Hi All,

I am trying to re project geometries using geoemtry service(4326 to 102100).Datum transformation is missing in ProjectAsync().
How to add transformation in service parameters?
Is there any alternative to re project geometry using silverlight API 2.4 and ArcServer 10.1?

Any help would be appreciated,
Prashant

Hi Prashant,

Here is a helper method you can user

If you'd like to use geom service, please take a look at the sample

Thanks,

Thanks Suba,

Example is useful to project only wgs_84(4326) to wgs84 web mercator (auxiliary sphere 3857).If source projection is different than 4326 then it won't re project properly.

geometryService.ProjectCompleted() doesn't provide datum transformation option.

Is there any alternative for datum transformation?

Prashant
