GUI description

The Graphical User Interface created in MATLAB (Version 6.5.0.1 8091 3a Release 13) provides access to the RAFOS dataset for viewing and interactive manipulation of the data.
The GUI capabilities:

easy access to the RAFOS database;
visualization of either all available, or an acquired subset of, RAFOS trajectories;
the ability to track float movement and retrieve the associated pressure and temperature information;
computation of Eulerian statistics (mean velocity and variance ellipse) for a cluster of trajectories within a customized rectangular region.

It is possible to run the GUI in MATLAB or as a stand-alone application outside of MATLAB.

If you have MATLAB installed on your computer,
you can run the GUI in MATLAB using
RAFOSgui source code (created in MATLAB 6.5),
given immediately below
PC WINDOWS users can run the GUI even they do not have
MATLAB installed on their computers using
MATLAB stand-alone application for WINDOWS,
given immediately below

You will also need M_Map: A mapping package for Matlab on your computer.

Add the directory with the unpacked RAFOSgui source code files to the MATLAB path.

It is necessary to have permission to write files to the current MATLAB directory (in which you put the RAFOSgui source code).

Start the GUI by typing traj in the MATLAB command line.

The process of data loading takes no more than 30 s for a Pentium 4 CPU, during which time the GUI is non-interactive.

Two main modes are possible using this GUI:

1) visualization of a single float trajectory;

2) drawing of all or parts of trajectories during some pre-defined time period

Visualization of pressure and temperature along float trajectories is available for both single and group modes:

The last diagram demonstrates the process of calculating and visualizing mean velocities and ellipses of variance (Freeland et al., 1975; Davis, 1991). All the trajectory fragments in a chosen region over a time instant use one-day time-steps. Because of the "accumulating" nature of this process, the beginning visualization should be considered as very approximate due to low statistical significance.
