• Basic description: Utilises splines and cubic interpolation to provide accurately and evenly sampled time-distance diagrams along complex curvilinear features.
• Language: IDL
• Resource needed to use: Desktop
• Host location: https://github.com/Richardjmorton/NUWT ¥ Current status: Complete
• 6-month plan to availability: N/A
• Status of documentation: Complete.
