Cartography: “The acquisition and manipulation of data culminating in its depiction in the form of a

map.”

GIScience: “the development and use of theories, methods, technology, and data for understanding

geographic processes, relationships, and patterns.”

• 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.
