The use of a background map and symbols that can be moved
in real time across the map, and which can be panned, zoomed and so
on, provide advanced map animation features.
There are graphics editing facilities provided by the Symbol Editor for JViews Diagrammer to help you create
your own custom symbols, see Developing
with design tools>Using the Symbol Editor.
Palettes of predefined symbols, some of which conform
to specific standards, such as APP-6a (MIL-STD 2525B) in the defense domain, are
also available. You can group symbols into hierarchies to define your
own symbology and for greater visibility against the map.
Optimized performance
Modern applications often require large map data sets
as satellite and Unmanned Aerial
Vehicles (UAV) views or exhaustive transportation networks
to realistically depict situations.
JViews Maps for Defense is optimized to efficiently
handle such large data sets to provide video-like performance while
minimizing memory requirements.
For example, by leveraging load-on-demand and dynamic data subsampling, the memory
footprint is minimized, even though the data contains millions of
objects. Display performance is based on disk and RAM caching as well
as advanced quadtree rendering and automated clipping and tiling.
This performance not only provides a better experience for the user,
but also saves processing time for other application CPU intensive
tasks.
You will be impressed by the reactivity of the interactive
zooming and panning, the storage and navigation facilities for Areas
of Interest, and the map rotation capability for GPS-like application
development.
Symbology
In addition to APP-6a symbols, JViews Maps for Defenseuses the rule-based presentation layer
of JViews Diagrammer to update
the appearance and position of assets when underlying application
data, such as status or positions, evolve. You can create your own
symbology and manipulate vector, raster, and complex objects. Symbols
support hierarchical logical grouping. See Developing with design tools>Using the Symbol Editor for
details of how to create your own symbols.
All the above features are directly available from the
component libraries.
Defense-specific symbology
JViews Maps for Defense provides the NATO standard APP-6a symbology library.

Decision support
JViews Maps for Defense has a powerful terrain analysis feature
to assist with decision making, whether in mission preparation or
on the battlefield during mission execution.
Terrain analysis provides sophisticated features such
as:
- Line of Sight, see Line of Sight
- Terrain Cut, see Terrain Cut
- 3D View, see 3D View
- Fly Through, see Fly Through
- Area of Sight, see Area of Sight (Approximate and Detailed views)
- Gradient, see Gradient Computation.
- Valley, see World map in GeoTIFF format.

There are APIs for data access and the integration of
custom algorithms.
These features can be applied in the heat of battle,
whether in formal conflict situations or partisan insurgency. They
can also be applied in the fight to preserve homeland security.
