Constructor Detail

StandardDTEDNameTranslator

public StandardDTEDNameTranslator()

Constructor for object to use for multiple translations.

StandardDTEDNameTranslator

public StandardDTEDNameTranslator(java.lang.String dtedDir,
                                  double lat,
                                  double lon,
                                  int level)

Set the internal parameters given a parent DTED directory, latitude, longitude and level. getName can be called to fetch a file name for these parameters.

Parameters:

dtedDir - the path to the top DTED directory.

lat - the desired latitude, in decimal degrees.

lon - the desired longitude, in decimal degrees.

level - the DTED level (0, 1, 2).

StandardDTEDNameTranslator

public StandardDTEDNameTranslator(double lat,
