First Claim
1. A moving map composer comprised of:
- means for storing a predetermined area representations of map coverages via bitmaps;
a reader for reading the bitmaps contained in the storage means;
means for controlling selection of the bitmaps from the storage means;
a computer for defining an aircraft optical disk image (AODI) by drafting a polygon defining any coverage;
determining the exact latitude/longitude and row/column extent of the coverage of the polygon;
calculating the exact size of a subdirectory and calculating the AODI side;
defining, viewing, and creating polar data;
adding or deleting desired segments of map coverage;
selecting the order of map sources used in building the AODI;
creating printouts including creation date, AODI name, AODI identification, map scale and AOD side;
selecting latitude/longitude grid intervals for printout and plot final AODI against a world map background;
merging multiple AODI'"'"'s into a single AODI; and
producing a final AODI display;
means for displaying the final produced by the AODI; and
means for recording the AODI image generated by the computer.

Abstract
The moving map composer (MMC) is a device that allows a user to manipulate different sources of map data into a single map for presentation on a display. The MMC has an ability to extract a predetermined area of map coverage defined by sets of latitude and longitude points, or non-orthogonal areas of map coverage, the smallest of which is a segment. A bitmap is a representation of an available map coverage for a given area selected by a user having a “set”, or “1” bit to indicate a segment is present, and a “clear”, or “0” bit to indicate a segment is missing. The size of the bitmap is determined dynamically to assure a two-bit buffer zone of clear bits around a polygon'"'"'s maximum extent. If the user selected polygon crosses one or more maps, the polygon is subdivided into several new polygons. Once the total map coverage desired has been defined, what available map sources are determined and the resulting subset is displayed, if the resulting coverage is acceptable, the user may transfer the data to the display.
