2. Halifax_AIS¶
Executing 1_run.py (shown below) will produce the following map.
Note that before you execute 1_run.py, you need to ensure that the
.basemap
and .grid
files were made before and are available (they
should be in the projects/example2_Halifax_AIS
directory). If not,
you have to make them using make_basemap.py. Note that the Halifax_Area
grid
is a “one-off” grid and this it is not in the /grids
directory (instead it is in the project directory).
Below are the contents of 1_run.py
