ObjectivesCompile topographic and imaging datasets into
Geographic Information Systems (GIS) databaseDifferent Datasets
MOLA (~462 meter per pixel) THEMIS (~100 meter per pixel)CTX (~6 meter per pixel)HiRISE (~1 meter per pixel)
Study small-scale surface characteristics of Arsia Mons lava flows to understand lava flow behavior and modification of lava flow surfaces by the wind and impact of craters

Fractal Dimensions of Lava Flow Margins- Arsia Mons flow segments span the ranges found for lava flows on Earth
- Lack of expected bimodal distribution due to complex margins at various scales
- Ongoing work: searching for correlations between fractaldimensions and different flow types
