PySCHISM

A Python interface for SCHISM model runs.

Installation:

Pre-requisites

It is highly recommended that you run this software using a Python virtual environment, and that you use Python>=3.6 (preferrably, using the latest available Python version is encouraged). You may use conda or venv to satisfy this dependency. You should also have the cdunits library installed. In ubuntu systems this is achieved by:

apt-get install udunits-bin

Install option 1: pip

pip install pyschism

Install option 2: clone repo

To install, clone this repository, and navigate into it:

git clone https://github.com/schism-dev/pyschism
cd pyschism

Then make sure to activate the target Python environment (this step is not necessary if you chose not to use a virtual environment). After making sure your target environment is active, you can install the package using pip:

pip install .

If you are a developer

If you are a developer, it is recommended that you clone the repo. After you add the -e flag to the pip install command in order to install in developer mode.

pip install -e .

hgrid.make_plot(show=True)

Example 2: Write mesh to QGIS friendly format

# NOTE: 2dm files can be read by QGIS > 3.0
from pyschism.mesh import Hgrid
hgrid = Hgrid.open('hgrid.gr3')
hgrid.write("/path/to/output/file.2dm", format='2dm')
