Transformation from one projection to other

[RahmathUnissa]

Hello,

I have created an app in Web Appbuilder, where the BaseMap has a spatial reference as say "A" and I using  a Map Service whose spatial reference as  say "B".

Q.1 How the Transformation from one projection to other is done?

Q.2 How can I get access to it? so that I can easily transform it in my widget.

Thank you.

Rathmath,

   You will use the GeometryService to project the geometry.

GeometryService | API Reference | ArcGIS API for JavaScript

Hey,

To Project a BaseMap in a Web AppBuilder  how do I give the below parameters:

params.outSR = outSR;

(Used  as  params.outSR = new SpatialReference({wkid:102100});  )

params.transformation = transformation;

Thank you,

You can not project a basemap, you project geometries to match your your basemaps WKID.
