JGOFS/GLOBEC Data Management System
Support for investigators at geographically different sites | ||
Client support for most (all?) computing platforms (PC, Macintosh, Unix, Linux) – Web based, using standard browsers | ||
Distributed data servers | ||
Data contributor directly controls data | ||
Always up to date | ||
Easier to grow computing resources | ||
But, can also use a central facility if one wishes |
Dissemination to scientific investigators on a timely basis | |
Data served when "useful" | |
Available to others outside the Program | |
Data use must follow data acknowledgement policy | |
Handle data, model output and images | |
Relationship to OPeNDAP (DODS) and value added web sites | |
What’s a data object? | ||
What are methods? | ||
Default method (defgb) | ||
Restructuring (rs) | ||
Combining with Perl scripts |
Data may reside on remote servers
Metadata is crucial for others to be able to use other investigator’s data. | |
This information comes from the contributing investigator(s). | |
To see the metadata, click on the text in the last column of the directory or on the “Documentation” button. |
Implementing Data Interoperability
Consistent field names | ||
You may get a call from George H. | ||
Global Change Master Directory (GCMD) and Directory Interchange Format (DIF) record (for data discovery) | ||
Enhancing JGOFS/GLOBEC software to use XML-based “info” file |
Selecting X-Y plotting options
Selecting just the field names you want | |
Try an on-line example |
Selecting out data with certain values | ||
temp < 4 and depth > 120 | ||
taxon contains calanus | ||

Set up by DMO several years ago. | |
DMAG advises DMO on issues such as field names and | |
units. | |

Data Visualization
Enhancements
Better Able to Handle:
Acoustic backscatter data (curtain plots) | |
Arbitrarily spaced scalar & vector data | |
Axes, labels, grids, bounding boxes | |
Underlying bathymetry surfaces | |
Multiple color maps for each object | |
Point-and-click object identification | |
3D thumbnails and list boxes for easier selection and previewing of variables |
Script file to load layers/colors/data points
Mark Benfield Stellwagon Bank abundance 3D gridded scalar field via kriging
Same view but with only higher density (counts) shown
Rotated view with different lighting
Curtain without points, rotated
Isosurfaces zoomed in but higher counts only
