NAME
loaddnmi - Load data from a DNMI file into a CODAS database

USAGE
loaddnmi control_file

DESCRIPTION
This utility was written for loading 2-D tide data from a numerical model into a CODAS database. These data were made available by the Norwegian Meteorological Institute (Det Norske Meteorologiske Institutt) where the name loaddnmi. Currently, only data files containing 2-D tide data is supported. The required producer definition file defining the database is DNMI_2DT.def.

PARAMETERS
The following parameters have to be defined in the control file:

dbname: database_name
    Name of database, eventually prefixed with the path to its location, if not in the current directory. Remember that the base name if a database should not exceed five characters.

prd_file: file
    Name and path of producer definition file defining the CODAS database.

OPTIONS
The following options are implemented:

OPTIONS:
    This key word can be used to improve the clarity of the control file and specify the beginning of options. It has no effect.

longitude_180
    Specify this for converting longitude values between -180 and +180 degree before using them.

grid_points= float
    In the case where data stored in the binary files refer to a polar stereographic map projection grid, the number of grid points from the Equator to the North Pole along the center meridian must be known for converting data back into geographical positions. Because files do not always have this parameter saved together with the data, this parameter must be provided separately.

time_range: range
    The time range in the usual format, i.e.

YYYY/MM/DD hh:mm:ss to YYYY/MM/DD hh:mm:ss

specifying which part of the data to load into the database. Note that this option must be specified.

position_range: range
    Position range specifying the area of selected data to load into the database. The format is the following:

lat1 lon1 to lat2 lon2

where latitudes and longitudes can be specified in the following formats:

{d}dd mm' ss.ss" S {d}dd mm.mmmm' S {d}dd.dddddd S S{d}dd.dddddd

where the optional leading digit d is for longitudes, the sign S is one of NSy+- for latitudes and EWX+- for longitudes. Hemisphere signs XY refer to bad positions and +- are used for the form where the sign S is placed in front of data. Note that this option must be specified.

end This keyword is mandatory and terminates the list of selected options.

LIST OF FILES
Finally, the control file is terminated by the list of DNMI files to parse.

OUTPUT FILES
The only files generated by this utility are the database files.
