Overview     Since the Jules Verne Voyager is based on the functionality of GMT (Generic Mapping Tools, developed and maintained by Paul Wessel and Walter H. F. Smith), data sets which are already in GMT format can be added very quickly. Some of the data sets listed here were already in a GMT format, others had to be massaged somewhat.

To date, planetary data or images mainly obtained from:

• ARC Science Simulations (Earth)
• NASA's Visible Earth (Earth)
• NASA's SeaWiFS Project (Earth)
• Washington University, St. Louis, Missouri, Planetary Data System (PDS) Geosciences Node (Earth, Moon, Mars, Venus, asteroids)

Datasets we're specifically looking for...    

• GPS or GLONASS velocity solutions of monuments in ITRF96 (or other) global reference frame
• global digital fault dataset for Earth
• high resolution digital grid data or images of any planetary body; we can probably handle up to 256 to 300 pixels/° (which would result in uncompressed RGB files totally 12.7 to 17.5 Gbytes in size for pole-to-pole coverage of a body)
• digital lon/lat outlines of non-circular features on planetary bodies

Do you have data that you would like to see in Voyager?     If you know of a public-domain data set which may be of general interest, feel free to contact us. Likewise, if you have a data set (even if proprietary) and would like to see it included in Voyager, please let us know; for example, we can make special arrangements to keep your data set safe and only allow users access via the GIF images displayed on users' browsers via Voyager, or even restrict access to certain data sets to specific IP addresses.

The data formats which are the most easily included in Voyager are:

• files already formatted for GMT
• point or line data in ASCII or binary format
• RGB, TIFF, PNG, GIF, or JPEG evenly-spaced lon/lat file showing some characteristic of all or some portion of a world (preference is RGB or TIFF format first, PNG or GIF second, JPEG last)
• binary or ASCII grid data of some single-valued function of longitude and latitude (e.g. DEM, gravity, geoid, seismic velocities, etc.), evenly spaced in lon/lat is best

• paths of famous explorations (e.g. Magellan, Cook, etc.)
• locations of hominid finds (with age of find, name of species/sub-species, etc.)
• whatever

Eventually, we hope to be able to set an ftp procedure where users can ftp data files to our site, for inclusion on Voyager imaging of Earth or other worlds, but with access limited to specific IP addresses, basically allowing only you and your colleagues to look at your own data with Voyager without necessarily contacting us.
