Overview    

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

Voyager Venus features     The default Venus uses a texture underlay grid grd=1 showing a Magellan synthetic aperature radar (SAR) composite image (gaps filled with lower-resolution Pioneer-Venus Orbiter data or a constant mid-range value) with simulated surface color based on Soviet Venera 13 and 14 surface images.

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

[Magellan SAR + color]		grd = 1		see above (0.0714° resolution)
[Magellan SAR grey]		grd = 2		grey-tone Magellan SAR image (0.0714° resolution)
[Radius (GTDR)]		grd = 9		planetary radius, derived from Magellan radar, GTDR dataset (0.044° resolution)
[Radius (smoothed)]		grd = 3		planetary radius, derived from Magellan radar, smoothed by spherical harmonic fit (1° resolution)
[Geoid]		grd = 6		geoid model, derived from Magellan orbit data, spherical harmonic fit (1° resolution)
[Geoid error]		grd = 8		geoid model error of above (1° resolution)
[Free air gravity]		grd = 5		free air gravity anomaly, derived from Magellan orbit data, spherical harmonic fit (1° resolution)
[Free air error]		grd = 7		free air gravity anomaly error of above (1° resolution)
[Bouguer gravity]		grd = 4		Bouguer gravity anomaly, derived from Magellan orbit data, spherical harmonic fit (1° resolution)
[Emissivity (GEDR)]		grd = 10		surface emissivity (ratio of radiant energy emitted by surface to that emitted by a blackbody at the same temperature), derived from Magellan radar, GEDR dataset (0.044° resolution)
[Reflectivity (GREDR)]		grd = 11		surface reflectity, derived from Magellan radar, GREDR dataset (0.044° resolution)
[Slope (GSDR)]		grd = 12		surface slope, derived from Magellan radar, GSDR dataset (0.044° resolution)

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

The image overlays available under [Missions:] (background material at Planetary Missions) are:

[site labels]	no thumbnail image	lbl = 1		names of all selected missions included on zoomed-in maps
[ancillary site data]	no thumbnail image	lbl = 2		(currently) dates of all selected missions included on zoomed-in maps
[USSR Venera sites]		mon = 1		sites of USSR Venera landings
[USA Pioneer Venus sites]		mon = 2		sites of USA Pioneer Venus atmospheric probe landings or impacts
[USSR Vega sites]		mon = 4		sites of USSR Vega landers

Note: Any grd, gmt, geo, lbl, vel, mon, msc, or opt code might change in the future, so be sure to check here for the current values!
