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.
Overview

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

We can use the time filter to see where this 1987 data lies in space…

Use Section Tool to select stations along a multi-segment path. In this example, stations are being selected along a depth contour.

Results of Section Tool: Note highlighted stations along depth contour and corresponding points in time/latitude panel.
