This package contains classes for reading Digital Aeronautical
Flight Information Files (see
DAFIF file). The format is a numerical map format for
aeronautical maps that is published by the National Geospatial Intelligence
Agency. The DAFIF readers provided in this package are based on DAFIF
specification Edition 8.
Basically, a DAFIF catalog covers the whole world with
aeronautical data. It is composed of a root directory (DAFIFT). This
root directory is divided into subdirectories, each corresponding
to a specific table set (ARPT, HLPT,IR,TZ,...). These subdirectories
contain the table description TXT files that make up the table set.
To find more information, you need to access the NGA
NIPRNET/Extranet. To access the NGA NIPRNET/Extranet, you need additional
access privileges granted by NGA. Register for access by going to
https://www.extranet.nga.mil.
There are two ways of reading DAFIF data:
Using an
IlvDAFIFReader instance directly. In this case, you must write
all the code required to render the DAFIF map features into graphic
objects, and then add them to the manager.
Using an
IlvDAFIFDataSource. This is a convenient way of performing all the
above operations at once and is more integrated with the data model
of the map.
