Overview

• The Problem
• Locating and selecting individual observations
  from a number of large collections of in-situ
  observations is complex.
• Designing software that makes this process
  intuitive for the user is challenging
• The Solution
• NdEdit,
• An intuitive, interactive Java tool
• For investigating the space-time relationship of
  in-situ data observations
• Provides graphical views of the locations of
  selected datasets in linked windows showing
  selected 2D views of space and time distribution
• Filtering, selecting, sub-setting, or zooming in
  one 2D view is reflected in the other views
• Provides interactive linked browsing of data
  locations in space and time
• E.g., a user can apply a narrow time filter in
  one window, and see the data locations in that
  time band in the latitude-longitude map view.

NdEditCustomized for in-situ data

• 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
