Application files
This package and its subpackages contain the application files that appear
in the IMG file-system.
The files that will be supported are
- TRE
- The tree view of the map that is needed to make sense of
the rest of the file. A map is divided into a number of different levels
of detail. At each level of detail it is divided into a number of areas
(called sub-divisions here. In general there will be more sub-divisions
at the better zoom levels. Each subdivision points to the ones in the
zoom level below it.
- RGN
- This file contains the definitions of the points, lines and polygons.
They have to be read in conjunction with the TRE section however,
as they don't make sense by themselves.
- LBL
- This file contains all the text lables. Other
files refer to the labels that are defined in this file.
