• Any data that has positional information
• Can be used to perform Exploratory Spatial Data Analysis (ESDA), apply geostatistical methods, create a map, etc.
• Not a cartographic product (map) or geovisualization.

• Generalization, regionalization, projective transformation, digitization, temporal provenance and representation tracking.
• How do you manipulate the data to prepare it for use in a Geographic Information System?

A P P L I C AT I O N S O F G I S & T
• Planetary cartography (Kirk, Williams, Grant)
• Geovisualization (DellaGiustina)
• Data collection (planning through acquisition), processing,and dissemination (McEwan, Chabot, A’Hearn, Beyer)
• Data storage and manipulation (Hare)
• Data accuracy and analysis (Archinal, Bleacher)
-
C O N C L U S I O N
• GIScience sits at the junction of many scientific endeavors (Colwell, 2004) • Spatially enabled data can be the keystone to facilitating cross domain
collaboration
• Fostering collaboration requires commonality in vocabulary; the definition of cartography is well established.
• A significant portion of the GIS&T BoK is directly applicable to the spatial work performed by the Planetary Science community.
