The y-scale origin is now displayed in bold on time-variable plots. A stacked-dots plot is now provided to assist in plot-locking (track dragging). The user can now load a default set of layers. 4-figure dates and multi-word track titles are now allowed in the REP file format. A grid with a user-specified origin, arc annotation with fill and plot-spokes options, and a new software installer were added.
This version adds a new worldwide gridded depth database, greatly improved 3-plotting (including realistic models of ships, submarines, helicopters, and aircraft), and track-shifting (typically used to synchronize submarine tracks). Many bugfixes have also been made.
Debrief 2001 adds the following major new features: Vectored chart & bathymetry data, Plotting sensor data, Managing narrative data, and Record to video.
