Voyager EarthScope features     The default EarthScope 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 DEM sources listed above)

The texture underlay grids available under [Features:] of Voyager: EarthScope are:

[Face of the Earth, relief]		grd = 1		see above (0.01° resolution)
[Topography, color, relief]		grd = 2		color-coded and shaded relief topography/bathymetry, based on GTOPO30, S+S v6.2, other (0.01° resolution)
[Topography, grey, relief]		grd = 3		grey-coded and shaded relief topography/bathymetry, based on GTOPO30, S+S v6.2, other (0.01° resolution)
[Greytone shaded relief]		grd = 4		grey-tone shaded relief topography/bathymetry, based on GTOPO30, S+S v6.2, other (0.01° resolution)
[Topography, grey]		grd = 5		grey-coded topography/bathymetry, based on GTOPO30, S+S v6.2, other (0.01° resolution)
[Topography, color]		grd = 6		color-coded topography/bathymetry, based on GTOPO30, S+S v6.2, other (0.01° resolution)
[Face of the Earth]		grd = 7		ARC Science Simulations' Face of the Earth ™ (0.01° resolution)
[Terra/MODIS]		grd = 8		true color, cloudless daytime view of continents and oceans, Terra satellite/MODIS sensor imagery (0.044° resolution)
[GSRM strain rate]		grd = 14		2nd invariant of strain-rate, International Lithosphere Project (ILP) Global Strain Rate Map (GSRM) Project, SUNY Stony Brook (0.2° resolution)
[EGM96, NASA geoid]		grd = 12		Earth Geopotential Model 1996 (EGM96), NASA geoid model, showing undulations from WGS-84 ellipsoid model (0.25° resolution)
[GSHAP, smooth]		grd = 20		Global Seismic Hazard Assessment Program (GSHAP) seismic hazard potential, raw data (not contoured) (0.1° resolution)

The standard image overlays available under [Features:] for optional longitude and latitude marking or distance scale bars are explained Advanced Help: generic options.
