I want to avoid duplicating effort.
Does ArcGIS Online have or intend to have one of these kinds of layers in the future.
- Open Street Map Vector Tiles including walking paths.
- Contours as vector tiles
I'm also willing to work with a third party that is doing this.
I know there are vendors like openmaptiles.com and MapBox but apparently, that's no good because ArcGIS Runtime will only work with Vector Tiles from ArcGIS servers or created with their tools.
