  1. The Ins and Outs of Planetary GIS Brian M. Hynek Laboratory for Atmospheric and Space Physics Department of Geological Sciences University of Colorado

  2. In the last 15 years, planetary exploration has taken off. • There are currently five spacecraft operating at Mars (2 on the ground, 3 in orbit). • Two additional successful missions. • The Moon is another target (Lunar Reconnaissance Orbiter, Chandrayaan-1, SELENE) • High resolution imaging, topography, elemental data. • The Cassini Mission is exploring the Saturn system since 2004. • UV-IR spectrometers, radar • MESSENGER will go into orbit around Mercury in 2011. • Laser altimeter, hyperspectral imager • GRAIL to the Moon, New Horizons to Pluto, Juno to Jupiter, etc…

  3. Types of data from Mars • Mars Global Surveyor – 1997-2007 • Visible imaging (few m/pix, >100,000 images) • Global topography grid (0.5 km/pix) • Thermal IR instrument for albedo and day/night thermal inertia (3 × 6 km pix). • Mars Odyssey – arrived 2001 • Gamma ray spectrometer, global 100 m/pix thermal IR data • Mars Express (ESA) – arrived 2004 • High-resolution stereo imaging (~20 m), shallow subsurface radar • 2 Mars Exploration Rovers – arrived Jan 2004 • Chemical/mineralogical spectrometers, imagery. • Mars Reconnaissance Orbiter – arrived 2006 • Contains 50 cm/pix camera and deep sounding radar.

  4. Mars’ global topography as understood 15 years ago

  5. Mars Global Surveyor Topography 500,000,000 data points

  6. MGS data and newly recognized VN Comparison of Viking and MGS data Viking image and previously mapped valley networks

  7. Viking-based VNs THEMIS-based VNs

  8. Planetary Geoscience: Worlds of Opportunity • Students love space and exploration. • Helps students go beyond their geocentric views. • Well-preserved surfaces to study tectonics, volcanism, hydrology, etc. • GIS for planetary applications is moving forward. • Web-based venues exist for easy access. • Lots of data are available – some at much better quality than terrestrial data.

  9. Best Resources • USGS Astrogeology Branch (Flagstaff) • Google Mars/Moon • Arizona State University • Global datasets and Java-based GIS server (JMARS)

  10. USGS Astrogeologyhttp://astrogeology.usgs.gov/Projects/webgis/(click on Maps, Tutorials, or Downloads • Planetary GIS resources for Mars, Moon, Venus, Galilean Satellites (Io, Europa, Ganymede, Callisto) • Arc-ready global datasets. • Web-GIS, tutorials, ftp dataset downloads, planetary GIS discussions, etc.

  11. Google Mars/Moon • Click on ringed planet in Google Earth. • http://maps.google.com/mars/ • Quick and dirty look at Mars with some place names and articles.

  12. JMARS (Java Mission-planning and Analysis for Remote Sensinghttp://jmars.asu.edu/ • Free Java-based “GIS” for Mars (and now the Moon). • Good for image searches. • Challenging learning curve, lack of help files/documentation for data. • Other ASU resources: • http://themis.asu.edu/maps global image search for multiple instruments • http://themis.asu.edu/topic images by geologic theme
