Data Access and Associated Tools: New MapServer Interface to the JGOFS/GLOBEC
Data Management System
U.S. GLOBEC Pan-Regional Synthesis Workshop

Data Management Office
• Make project data available on-line– Hunting the data and information down– Quality control– Find and document the metadata– Add data to the JGOFS/GLOBEC system– Data are freely available; must abide by
data acknowledgment policy
U.S. GLOBEC Pan-Regional Synthesis Workshop

• Facilitate data access and synthesis– JGOFS/GLOBEC data management system
• Data objects• Directory structure• Download capability• Simple X-Y plotting
– Distributed data servers– Software is open source, freely available– DIF records submitted to the
Global Change Master Directory

Key Data Policy Characteristics
• Dissemination to scientific investigators on a timely basis
• Available when "useful"
• Available to others outside the program

JGOFS/GLOBEC uses a text based interface
• Supports all web browsers
• Distributed servers for ASCII and image data using httpd protocol
• Simple, list oriented interface with basic X-Y plotting capabilities
