A Classic Example
5
National Current Observation Program

• Provide Data for
• Navigation
• Search and Rescue/HAZMAT
• Coastal Estuarine Circulation

• Tidal Current Predictions from
• Area Surveys
• Real Time in Shipping Channels

Tidal Current Tables
6
Why?

• Increasing data flow
• Yearly increase in the number of data collection
  sites
• Increasing temporal resolution
• Increasing spatial resolution
• Collaboration
• Distributed Data Sets
• Various Numerical Units
• Various File Formats
• Antiquated Computer Software

7
Capability Maturity Model (CMM)

• CMM Level 3 The development process follows
  well defined rules and methods
• Tracks time and progress
• Method for attaining a quality of the final
  product
• Robust Project Planning
