hspf_reader - Quick Guide

The hspf_reader is a pure Python module and command line script to read HSPF time-series from WDM files, HSPF binary files, and HSPF plotgen files.

Use “wdmtoolbox” to create, examine, read, and write to WDM files.

Use “hspfbintoolbox” to catalog and read HSPF binary output files.

Installation

pip

pip install hspf_reader

conda

conda install -c conda-forge hspf_reader

Usage - Command Line

Just run ‘hspf_reader –help’ to get a list of subcommands:

usage: hspf_reader [-h]
                 {wdm, hbn, plotgen, about} ...

positional arguments:
  {wdm, hbn, plotgen, about}

wdm
    Read HSPF WDM files.
hbn
    Read HSPF binary files.
plotgen
    Read HSPF plotgen files.
about
    Display version number and system information.

optional arguments:
  -h, --help            show this help message and exit

The output time-series data is printed to the screen and you can then redirect to a file.

Usage - API

You can use all of the command line subcommands as functions. The function signature is identical to the command line subcommands. The return is always a PANDAS DataFrame.

Simply import hspf_reader:

from hspf_reader import hspf_reader

# Then you could call the functions
ntsd = hspf_reader.wdm('wdm_file.wdm', 202)

# Once you have a PANDAS DataFrame you can use that as input to other
# hspf_reader functions.
ntsd = hspf_reader.hbn('hbn_file.hbn', "yearly", [,,,"TAET"])
