com.bbn.openmap.layer.rpf.RpfCoverageBox
The RpfCoverageBox describes the coverage provided by a RpfTocEntry within a table of contents file. This should be enough information that lets you tell what you need to ask for the proper subframes to put on a screen.

    protected CRFPCoverageBox[] vectorToCRFPCoverageBoxes(Vector vector) {
        int size = vector.size();
        CRFPCoverageBox[] rets = new CRFPCoverageBox[size];


        for (int i = 0; i < size; i++) {
            RpfCoverageBox box = (RpfCoverageBox) vector.elementAt(i);
            if (box != null) {
                rets[i] = new CRFPCoverageBox((float) box.nw_lat, (float) box.nw_lon, (float) box.se_lat, (float) box.se_lon, box.subframeLatInterval, box.subframeLonInterval, box.chartCode, (short) box.zone, new XYPoint((short) box.startIndexes.x, (short) box.startIndexes.y), new XYPoint((short) box.endIndexes.x, (short) box.endIndexes.y), (short) box.tocNumber, (short) box.entryNumber, box.scale, box.percentCoverage);
            }
