Why Hydrodata?
--------------

Hydrodata is a stack of Python libraries designed to aid in watershed analysis through
web services. Currently, it only includes hydrology and climatology data within the US.
Some of the major capabilities of Hydrodata are:

* Easy access to many web services for subsetting data and returning the requests as masked
  xarrays or GeoDataFrames.
* Splitting large requests into smaller chunks under-the-hood since web services usually limit
  the number of items per request. So the only bottleneck for subsetting the data
  is the local available memory.
* Navigating and subsetting NHDPlus database (both meduim- and high-resolution) using web services.
* Cleaning up the vector NHDPlus data, fixing some common issues, and computing vector-based
  accumulation through the network.
* A URL inventory for some of the popular (and tested) web services.
* Some utilities for manipulating the data and visualization.

You can visit `examples <https://hydrodata.readthedocs.io/en/develop/examples.html>`__
webpage to see some example notebooks. You can also try using Hydrodata without installing
it on you system by clicking on the binder badge below the Hydrodata banner. A Jupyter notebook
instance with the Hydrodata software stack pre-installed will be launched in your web browser
and you can start coding!

Please note that since Hydrodata is in early development stages, while the provided
functionaities should be stable, changes in APIs are possible in new releases. But we
appreciate it if you give this project a try and provide feedback. Contributions are most welcome.

The full documentation can be found at https://hydrodata.readthedocs.io.

Features
--------

Hydrodata itself has three main modules; ``hydrodata``, ``plot``, and ``helpers``.
The ``hydrodata`` module provides access to the following web services:

* `NWIS <https://nwis.waterdata.usgs.gov/nwis>`__ for daily mean streamflow observations,
* `HCDN 2009 <https://www2.usgs.gov/science/cite-view.php?cite=2932>`__ for identifying sites
  where human activity affects the natural flow of the watercourse,
* `NLCD 2016 <https://www.mrlc.gov/>`__ for land cover/land use, imperviousness, and canopy data,
* `SSEBop <https://earlywarning.usgs.gov/ssebop/modis/daily>`__ for daily actual
  evapotranspiration, for both single pixel and gridded data.

Also, it has two other functions:

* ``interactive_map``: Interactive map for exploring NWIS stations within a bounding box.
* ``cover_statistics``: Compute categorical statistics of land use/land cover data.

The ``plot`` module includes two main functions:

* ``signatures``: Plot five hydrologic signature graphs.
* ``cover_legends``: Return the official NLCD land cover legends for plotting a land cover dataset.

The ``helpers`` module includes:

* ``nlcd_helper``: A roughness coefficients lookup table for each land cover type which is
  useful for overland flow routing among other applications.
* ``nwis_error``: A dataframe for finding information about NWIS requests' errors.

Moreover, requests for additional databases and functionalities can be submitted via
`issue tracker <https://github.com/cheginit/hydrodata/issues>`__.

Installation
------------

You can install Hydrodata using ``pip`` after installing ``libgdal`` on your system
(for example, in Ubuntu run ``sudo apt install libgdal-dev``):

.. code-block:: console

    $ pip install hydrodata

Alternatively, Hydrodata can be installed from the ``conda-forge`` repository
using `Conda <https://docs.conda.io/en/latest/>`__:

.. code-block:: console

    $ conda install -c conda-forge hydrodata

Contributing
------------

Hydrodata offers some limited analysis tools. It could be more useful for
the watershed modeling community to integrate more data exploratory and analysis
capabilities to the package. Additionally, adding support for more databases such
as water quality, phenology, and water level, are very welcome. If you are interested
please get in touch. You can find more information about contributing to Hydrodata at our
`Contributing <https://hydrodata.readthedocs.io/en/latest/contributing.html>`__ webpage.
