pathΒΆ
This program is used to calculate the drift of a set of points using geostrophic velocity fields.
This program uses a configuration file similar to the configuration file used by the program map_of_fle.py and tabular ASCII file that contains:
on the first column the longitude of the point in degrees and
on the second column the latitude of the point in degrees.
To launch the propagation of points over the velocity fields, execute the following command:
path.py list.ini buoys.txt "2010-01-01" "2010-01-02"
The program run shows the following lines:
