| Sep 17, 2018 at 18:57 | comment | added | mkennedy | If you add the raster to ArcMap and look at the data frame properties, coordinate system tab, can you get the spheroid (ellipsoid) information? That may or may not help us give you an answer. | |

| Sep 17, 2018 at 18:54 | comment | added | nyquist | You have to declare the output datum. There is a WGS 84 datum you can use. See this answer for more info on projections and datums | |
