Voyager Mars features     The default Mars uses a texture underlay grid grd=1 showing a Viking orbiter color composite image. Modern shape data (e.g. topography and radius) is from Mars Global Surveyor (MGS)/Mars Orbital Laser Altimeter (MOLA); one texture underlay grid is from MGS/Mars Orbiter Camera (MOC). These data and derived models can be compared with earlier (and lower resolution) ones based on Viking orbiter and the Mariner 9 flyby.

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

[Viking composite]		grd = 1		Viking orbiter color composite image (0.0156° resolution)
[MOLA topo: color w/ relief]		grd = 2		MGS)/MOLA color-scaled topography with shaded relief (0.0156° resolution)
[MOLA topo: grey relief]		grd = 3		MGS/MOLA topography, greytone shaded relief (0.0156° resolution)
[MOLA topo: color]		grd = 4		MGS/MOLA topography, color-scaled only (0.0156° resolution)
[ (Viking-Mariner9 topo)]		grd = 5		Viking orbiter and Mariner 9 composite topographic model, color-scaled only (1° resolution)
[Viking + MOLA]		grd = 6		Viking color composite image mixed with MOLA topographic model (0.148°x0.151° resolution)
[MOC, red band]		grd = 23		MGS/MOC Geodesy Campaign Mosaic, red band shown in greytone; no data from ~62°S - 65°S (0.004° resolution)
[MOLA radius]		grd = 7		MGS/MOLA derived planetary radius (0.0156° resolution)
[ (Vik-Mar9 radius)]		grd = 8		Viking orbiter and Mariner 9 derived planetary radius (1° resolution)
[MOLA areoid-ellipsoid]		grd = 21		MGS/MOLA derived areoid (geopotential surface) model wrt ellipsoid, 3396x3378.2 km radii (0.0156° resolution)
[ (Vik-Mar9 areoid-ellipsoid]		grd = 22		Viking orbiter and Mariner 9 derived areoid model wrt ellipsoid, 3396x3378.2 km radii (1° resolution)
[MOLA areoid-sphere]		grd = 9		MGS/MOLA derived areoid (geopotential surface) model wrt 3396-km spherical radius(0.0156° resolution)
[ (Vik-Mar9 areoid-sphere)]		grd = 10		Viking orbiter and Mariner 9 derived areoid model wrt 3396-km spherical radius (1° resolution)
[MOLA free-air anomaly]		grd = 13		MGS/MOLA derived free-air gravity anomaly (0.125°x0.139° resolution)
[ (Vik-Mar9 free-air)]		grd = 14		Viking orbiter and Mariner 9 derived free-air gravity anomaly (1° resolution)
[ (Vik-Mar9 Bouguer)]		grd = 16		Viking orbiter and Mariner 9 derived Bouguer gravity anomaly (1° resolution)
[ (Vik-Mar9 crustal thick.)]		grd = 18		Viking orbiter and Mariner 9 derived crustal thickness model (1° resolution)
[MOLA moho depth]		grd = 19		MGS/MOLA derived moho (crust-mantle boundary) depth (0.125°x0.139° 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 Mars sites]		mon = 1		sites of USSR "Mars" probe landings and crashes
[USA Viking sites]		mon = 2		sites of USA Viking landings
[USA Pathfinder site]		mon = 4		site of USA Pathfinder lander and Sojourner rover
[USA Polar Lander site]		mon = 8		probable site of USA Polar Lander crash
[USA Deep Space 2 site]		mon = 16		possible site of USA Deep Space 2 impact probes Amundsen and Scott (deployment was part of the failed Polar Lander mission)
[ESA/UK Beagle 2 site]		mon = 64		planned landing site of ESA/UK Beagle 2
[USA MER sites]		mon = 32		landing sites of USA Mars Exploration Rovers (MER): Spirit and Opportunity
[USA Phoenix site]		mon = 128		landing site of USA Phoenix lander

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!
