Research Question

• How can multiple linked views (MLVs) applied to
  terrestrial lidar data of rock art and
  surrounding weathering forms extract new insight
  of rock instability associated with rock art
  panels?

Conclusion

• Exploration and classification of complex,
  multivariate geographic phenomena are facilitated
  with interactive box plots and MLVs
• Management decisions related to rock art
  preservation are justified based on quantitative
  characterizations of rock surfaces
• May prove useful outside of the rock art
  preservation community
