What is PSICAT?

• PSICAT is a Java-based graphical editing tool for
  creating and viewing core description diagrams.
  It captures data as you draw and provides various
  visualization and analysis options.

Core Description (2)

• Primary record of the core
• Traditionally drawn by hand
• Drafted in a graphics application
• Good for publication
• Harder to work with when you want data

7
Technical Details (1)

• Captures the data e.g. depths, grain sizes,
  lithologies, behind what you draw
• Integrate images and external data sets into your
  diagrams
• Open source, cross platform
• Designed to be modularpick and choose only the
  pieces you need
• Can easily be extended to capture new data or
  provide new visualizations and analyses
