Abstract

The Pele-Pillan region of Jupiter’s moon Io is an area of high volcanic activity. The active lava lake Pele and the characteristic fire fountain and turbulent flows of Pillan produce some of the highest thermal outputs for this moon. Planetary scientists do not currently have a means of efficiently processing the surface temperature data captured of this region for incorporation into a geographic information system (GIS). A GIS of the Photopolarimeter-Radiometer (PPR) surface temperature data, that was captured in the late 1990s and the early part of this decade by the Galileo spacecraft, can aid in the visualization and analysis of volcanic activity on Jupiter’s moon Io. Current PPR data processing techniques required enhancement and an automated workflow was needed in order to create a complete GIS for Io by the United States Geological Survey deadline of July 2011. This paper focuses on the development of a prototype ArcGIS toolkit for processing PPR data of Io’s highly active Pele-Pillan region. The toolkit uses Visual Basic and ArcObjects programming components to: 1) create features in ArcGIS, representing temperature scans of Io’s surface, and 2) generate new color-coded, temperature-specific symbology for these features.
