MapView Viewpoint changes from v200.5.1 -> v200.6

Hi, 

We found that there are quite observable changes in MapView when we set the Viewpoint using the same Envelope

Please see attached images.

The coloured rectangle is an GraphicsOverlay inside ArcGIS

The line with 2 circles are drawn on top and of the map, and they do not move between versions.

Note that only the map(and rectangle) is different between versions even with the same viewpoint.

 

This is the code we use:

 

mapViewProxy.setViewpoint(Viewpoint(boundingGeometry: Envelope(center: center, width: size, height: size)), duration: 0)

 

With these variables:

center = Point(latitude: 47.38776035242992, longitude: 8.6554592857211)

zoomedInSize = 0.00034594444524398035

zoomedOutSize = 0.0010085843884744825

 

 

We have been using ArcGIS since v100, and only in v200.6.0 is this change observed

 

Is this a bug? Or perhaps something changed with the way MapView is rendered?

Hi @John_G, this is an expected behavior change where available coordinate systems and transformations have been updated to EPSG v11.015 as mentioned in the 200.6 release notes. In the example you gave using the Samples app, the map view performs an implicit projection because the map has a web mercator spatial reference and the geometry used to set the viewpoint has a WGS84 spatial reference.
