ArcGIS Online adds support for planetary layers

18 May 2017 Several from NASA and the USGS worked with Esri to include several planetary bodies into their ArcGIS Online mapping environment. While planetary layers have been cataloged on ArcGIS Online for several years, and functioned properly in ArcMap and ArcGIS Pro, the javascript measurement tools (scalebar and measurement widgets) available from the ArcGIS Online interfaces were hard-wired to Earth. These tools now respect several non-Earth spheroids (e.g. Mercury, Mars, Venus,...) when defined in live ArcGIS Server layers and layers as hosted on ArcGIS Online.
