  3. Overview of JOA Features • Cross Platform • Windows, Solaris, Mac OS 9/X, Linux

  4. Overview of JOA Features • Sophisticated exploration of profile data • Linked browsing between all plot types • User interface is friendly, but offers many options • Color as a third variable • All plots resizeable and zoomable • No limit on number of open windows • Informative default interface • Full user customization • Includes NdEdit for data selection from large data collections • Large number of supported profile data formats for bottle and CTD data

  5. Overview of JOA Features • Property-Property Plots • Property-property plots with up to 3 x-axes • Isopycnal overlay

  6. Overview of JOA Features • Profile Plots • Offset property-property profiles (waterfall plots)

  7. Overview of JOA Features • Contour Plots • Contoured sections (e.g., depth sections) • Referenced and residual contour plots

  8. Overview of JOA Features • Map Plots • Multiple projections • Station symbols colored by properties interpolated onto multiple surfaces (e.g., pressure or density) • Bathymetry display: isobaths, ETOPO, Sandwell-Smith • Tools to create custom sections

  9. Overview of JOA Features • Customization • Color bars • Color palettes • Interpolation surfaces • Custom coastlines and bathymetry • Saved map settings • CTD Decimation • Fixed levels, JOA surface levels, or custom levels • Sophisticated import of WOCE “Exchange” files • Calculations • Observation Calculations • Simple Custom Calculations • Transformations • Station Calculations • Filters • Station Filters • Observation Filters

  10. NdEdit Unique Interactive Java Tool For In-situ Data Linked windows show xy, xt, zx views of data locations, filter or select with box, polygon or segmented line tools http://www.epic.noaa.gov/talks/oz/ams2002/http://www.epic.noaa.gov/epic/software/JavaNdedit.htm

  11. NdEdit • Java tool • Platform independent • Java Bean architecture allows integration with other tools • Linked windows • Choice of 2D views: latitude-longitude (map), latitude-depth, latitude-time, longitude-depth, longitude-time, and depth-time • Interactive with zoom • Map Features • Overlay bathymetry • Overlay coastlines • Filter or subset data • Browse time-space distribution of in-situ data • Filter in any 2D view • Time or space (lat, lon, z) filters • Remove or retain stations in filter region • Selection Tools • Box • Polygon • Multi-segment section line with user-settable width • Single station selection • Non-contiguous selections • Tools work in all 2D views

  12. JOA Demo

  13. Integrating JOA/NdEdit With DODS • NdEdit First Step • Local DODS pointer files: paths replaced by URLs • DODS-driven features in NdEdit • - Interact with DODS catalogs to create pointer files on the fly • JOA First Step • Access netCDF profiles over the internet by supporting http features of netCDF2 • DODS-driven features in JOA • Comparison of local data sets with online resources • Extract sections from n-dimensional datasets
