Overview    

See Getting Started for a quick overview of the Jules Verne Voyager map tool capabilities.

For items specific to voyaging Earth, continue to read this Earth Features Help page.

To learn how to use the grd, gmt, geo, lbl, vel, mon, msc, and/or opt codes to customize a starting view, see Advanced Help: URL customizing.


Voyager Earth features     The default Earth uses a texture underlay grid grd=1 showing

  • above sea level: ARC Science Simulations' Face of the Earth ™ (based on NOAA-11 image data from 1992; natural surface colors of the Earth, pole-to-pole, cloud-cover eliminated, snow-cover minimized) mixed with shaded relief (derived from GTOPO30 DEM, Sandwell and Smith bathymetry v6.2, and various polar bathymetry DEMs circa 1998)

  • below sea level: color-coded and shaded relief bathymetry/topography (derived from same DEM sources as above)
