WRES Explorer

Utilities to visualize and explore output from the NOAA Office of Water Prediction's (OWP) Water Resources Evaluation Service (WRES).

Installation

In accordance with the python community, we support and advise the usage of virtual environments in any workflow using python. In the following installation guide, we use python's built-in venv module to create a virtual environment in which the tool will be installed. Note this is just personal preference, any python virtual environment manager should work just fine (conda, pipenv, etc. ).

# Create and activate python environment, requires python >= 3.10
$ python3 -m venv venv
$ source venv/bin/activate
$ python3 -m pip install --upgrade pip

# Install nwis_client
$ python3 -m pip install wres.explorer

Application Interface

The application features a tabbing interface. The "File Selector" tab is active by default.

File Selector

The file browser starts in the directory where the application was launched. Use the arrows to move the files you want to visualize from the "File Browser" to the "Selected files".

The example below has selected the file ABRFC.evaluation.csv.gz. After selecting one or more files, click the "Load/Reload Data" button to read the files.

Metrics Table

Once data are loaded, you will be able to explore the file(s) contents through a paging tabular interface shown below.

Feature Selector

To inspect the metrics at a specific feature (site), you need to select a feature from the selection boxes or by clicking on the map. The available options are determined by the features found in the files you selected earlier. Note the selected site in magenta.

Metrics Plots

After a site is selected, the "Metrics Plots" tab will be populated with plots showing the metrics found at this feature. Use the dropdown menu ("Select Metric") to view different metrics.
