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 -<n/s> <value>.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 -<w/e><value>.

Parameters:

lon - longitude in decimal degrees.

Returns:

part of the DTED directory path that longitude contributes to.
