### DTEDFrameUtil

    public DTEDFrameUtil()

Method Detail

### stringToLat

    public static float stringToLat(java.lang.String text_lat)

  Conversion of string found in DTED file to float value.

  Parameters:
    `text_lat` - the String representation of the latitude, from the file.
  Returns:
    the latitude in decimal degrees.

### stringToLon

    public static float stringToLon(java.lang.String text_lon)

  Conversion of a string value of a longitude to a float.

  Parameters:
    `text_lon` - the longitude String representation, out of a DTED file.
  Returns:
    the longitude in decimal degrees.

### latToFileString

    public static java.lang.String latToFileString(float lat,
                                                   int level)

  Conversion of a float latitude value and DTED level to a DTED filename. DTED filenames are based on these two factors - .dt{0,1} DTED Level 0 files are named .dt0. Level 1 and higher are named .dt1, rather than .dt{level}

  Parameters:
    `lat` - latitude in decimal degrees.
    `level` - the DTED level.
  Returns:
    part of the DTED directory path that longitude contributes to.

### lonToFileString

    public static java.lang.String lonToFileString(float lon)

  Conversion of a float longitude value to a DTED parent directory of frame files. DTED parent directories are based on latitude -.

  Parameters:
    `lon` - longitude in decimal degrees.
  Returns:
    part of the DTED directory path that longitude contributes to.
