Hello,
I wasn't sure what product category to post this question under, so I'll just start here and see where it goes.
1. I'm trying to create a native mobile app using 3D Web Scenes and/or Mobile Scene Packages (mspk) configured in ArcGIS Pro.
2. The 3D scenes feature bathymetric seafloor models with 100ft spaced contours (polylines).
3. The ArcGIS Pro map is a Global Scene - WGS 1984 (Geographic spatial reference).
4. I set the crs for all the layers in the Global Scene to be WGS 1984.
5. Now AFIK the only way to make the ArcGIS Pro Web Scene/mspk layers available for download to the ArcGIS Web AppBuilder is to stage them in ArcGIS Online.
6. When the Web Scene/mspk is shared/published to ArcGIS Online, all layers are reprojected from WGS 1984 (Geographic coordinates system) to WGS 1984 Web Mercator (auxiliary sphere)
7. I’m able to view the scenes in ArcGIS Scene Viewer with the contour layers displaying as expected.
8. When the scene is downloaded to ArcGIS Web AppStudio and loaded into the Player app, the contours are missing. Not sure the exact cause, but I think because they are assigned the WGS 1984 Web Mercator (auxiliary sphere) coordinates reference system, which isn’t supported in ArcGIS Web AppStudio (I think?). However, the other layers, like elevation and raster overlays have the 1984 Web Mercator (auxiliary sphere) coordinates reference system assigned as well and they display in the Player app, so I’m confused.
