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:
