Project description
hf_hydrodata
Python component to access data in the hydrodata hydrology file share.
Installation
The best way to install hf_hydrodata
is using pip. This installs our
latest stable release with fully-supported features:
pip install hf_hydrodata
Documentation
You can view the documentation at ReadTheDocs.
Usage
You can use hf_hydrodata
to get access to both gridded and point observation data from various
datasets available in hy_hydrodata.
You can view the available datasets and variables from the documentation or you can get the list of dataset and variables from functions.
import hf_hydrodata as hf
datasets = hf.get_datasets()
variables = hf_get_variables()
variables = hf.get_variables("dataset": "NLDAS2", "grid": "conus1")
You can get gridded data using the get_gridded_data() function.
import hf_hydrodata as hf
options = {
"dataset": "NLDAS2", "variable": "precipitation", "period": "hourly",
"start_time": "2005-10-1", "end_time": "2005-10-2", "grid_bounds": [100, 100, 200, 200]
}
data = hf.get_gridded_data(options)
You can use the point
module to read site-level observations data from the hydrodata repository to get a
pandas DataFrame.
hf_hydrodata
supports access to a collection of site-level data from a variety of sources.
The below syntax will return daily USGS streamflow data from January 1, 2022 through January 5, 2022 for sites that are within the bounding box with latitude bounds of (45, 50) and longitude bounds of (-75, -50).
# Import package
from hf_hydrodata.point import get_data, get_metadata
# Define filters and return as pandas DataFrame
data_source = 'usgs_nwis'
variable = 'streamflow'
temporal_resolution = 'daily'
aggregation = 'average'
data = get_data(data_source, variable, temporal_resolution, aggregation,
start_date="2022-01-01", end_date="2022-01-05",
latitude_range = (45, 50),
longitude_range = (-75, -50))
data.head(5)
# Get the metadata about the sites with returned data
metadata = get_metadata(data_source, variable, temporal_resolution, aggregation,
start_date="2022-01-01", end_date="2022-01-05",
latitude_range = (45, 50),
longitude_range = (-75, -50))
metadata.head(5)
Build Instructions
To build the component you must have a python virtual environment containing the required components. Install the required components with:
pip install -r requirements.txt
Edit the python components in src/hf_hydrodata
and the unit tests in tests/hf_hydrodata
and the data catalog model CSV files in src/hf_hydrodata/model
.
Use Excel to edit the CSV files so that files are saved in standard CSV format.
Generate the documentation with:
cd docs
make html
This will validate the model CSV files and generate the read-the-docs html into the html folder.
