IP. |
Data Display Tools. Data at all levels can be displayed on plots controlled by simple graphical user interfaces. For example, raw or averaged cross spectra can be plotted in 3D color form or as time-series/spectral curves. Wave data have several formats for display. Radial and total current-vector map algorithms include coastlines and bathymetry contours, with several full-color options for vector and uncertainty displays. The latter tools also permit easy creation of movies over time, and vector density coverage distributions for diagnosis. Touching the screen with a mouse-click, for example, gives a numerical value for any vector or uncertainty at that point.
SeaDisplay. Plot total, radials and ellipticals over coastline site map. create and modify total vector grid. create image output. create movies over time.
Vector display software allowing statistical analyses of multiple current-map data sets and their errors that will compute statistics (i.e., means, root-mean-square differences, and standard deviations) over a period of time as user selects.
WaveDisplay is another useful application used to visualize wave data gathered by CODAR systems. WaveDisplay can plot wave time series from one range cell or multiple ranges in one display
Data Transfer Software & Protocols. Both the central site and radial/remote sites come equipped with several tools that facilitate scheduling and executing data transfers. Software (such as Timbuktu) delivered will also permit interactive control and transfers between any site to any location in the world. This software has been refined after many years and thousands of hours of use.
Movie making capability that allows users to make a movie of vector fields or radial velocity maps over any period for which data were observed.
Drift and trajectory calculation and plot display movies.
Tidal Analysis tool. |
