EarthPy makes it easier to plot and manipulate spatial data in Python.

Why EarthPy?

Python is a generic programming language designed to support many different applications. Because of this, many commonly performed spatial tasks for science including plotting and working with spatial data take many steps of code. EarthPy builds upon the functionality developed for raster data (rasterio) and vector data (geopandas) in Python and simplifies the code needed to:

EarthPy also has an io module that allows users to

  1. Quickly access pre-created data subsets used in the earth-analytics courses hosted on www.earthdatascience.org
  2. Download other datasets that they may want to use in their workflows.

EarthPy's design was inspired by the raster and sp package functionality available to R users.

Install

EarthPy can be installed using pip, but we strongly recommend that you install it using conda and the conda-forge channel.

Install Using Conda / conda-forge Channel (Preferred)

If you are working within an Anaconda environment, we suggest that you install EarthPy using conda-forge

$ conda install -c conda-forge earthpy

Note: if you want to set conda-forge as your default conda channel, you can use the following install workflow. We recommmend this approach. Once you have run conda config, you can install earthpy without specifying a channel.

$ conda config --add channels conda-forge
$ conda install earthpy

Install via Pip

We strongly suggest that you install EarthPy using conda-forge given pip can be more prone to spatial library dependency conflicts. However, you can install earthpy using pip.

To install EarthPy via pip use:

$ pip install --upgrade earthpy

Once you have successfully installed EarthPy, you can import it into Python.

>>> import earthpy.plot as ep

Below is a quick example of plotting multiple bands in a numpy array format.

>>> arr = np.random.randint(4, size=(3, 5, 5))
>>> ep.plot_bands(arr, titles=["Band 1", "Band 2", "Band 3"])
>>> plt.show()
