Illustrates how to import data from a Vector Product Format (VPF) database into World Wind. This uses
to display an imported VPF database, and uses
to enable the
user to choose which shapes from the VPF database to display.
To display VPF shapes with the appropriate color, style, and icon, applications must include the JAR file
in the Java class-path. If this JAR file is not in the Java class-path, VPFLayer outputs
the following message in the World Wind log:
WARNING: GeoSym style support is disabled
. In this case,
VPF shapes are displayed as gray outlines, and icons are displayed as a gray question mark.
