GES DISC Interactive Online Visualization and ANalysis Infrastructure (Giovanni) Online Users Manual:   Suggestions for Formatting Graphics and Data for Reports and Publications

Suggestions for Formatting Graphics and Data for Reports and Publications

This section of the Giovanni Online Users Manual provides examples of how Giovanni output can be adapted for scientific presentations, such as reports, posters, and publications.     As the developers create new ways to visualize the data, additional information will be added to this page.

8.1  Graphics Output Modifications

Graphics output can be modified by cropping the header and axis labels and replacing them with user-specified information in a variety of image processing software.   The following is an example of Giovanni output graphics modified for a research publication.

Chesapeake Bay Hovmoller plots from Acker et al. 2004

The Customized color palette option allows the creation of a single color palette for multiple output graphics, so that the same color bar can be used for a figure with several different plots.    The use of different color palettes that may be generated by the Dynamic option can be confusing and make comparison of graphic plots more difficult.   The color scale created for these plots appears below the plots.

Image processing software can be used simply to illustrate a study region of interest, as shown below.  This plot is of the "Chlorophyll a concentration anomaly", a SeaWiFS data type selection.

8.2  ASCII Output Graphics

The use of ASCII Output data in software packages (such as spreadsheet programs) allows plotting of multiple data sets on a single figure, as demonstrated below.

Chesapeake Bay data, minimum, maximum, average values, time plot

The "MIssion Avg" data plotted in this figure also utilized the ASCII Output option.   The average data value for the study region was generated for each month separately (i.e, January 1998, January 1999, January 2000, to the end of the data set) and then the data values provided by Giovanni were averaged together and plotted with the annual data shown here.
