HEC-DSS, is a database system designed by U.S. Army Corps of Engineers' Hydrologic Engineering Center to efficiently store and retrieve typically sequential scientific data. HEC-DSS is incorporated into most of HEC’s major application programs like HEC-HMS, HEC-RAS etc.
record types implemented in pyheclib are:
- Time Series Data (Regular & Irragular)
- Paired Data
# on ubuntu 18.04/20.04
$ pip3 install https://github.com/nzahasan/pyheclib/zipball/master
# on windows requires MS visual c++ 14 build tools & inter fortran compiler
Example given below shows how to read & write regular time series:
import pyheclib as phl
import numpy as np
reg_data = np.array([13.21, 44.21, 13.24, 55.21,88.76,77.33])
ts_cnt = phl.tseries()
ts_cnt.regular(
"/BASIN/LOCATION/FLOW//3HOUR/TEST/",
reg_data,
"01Jan2020",
"06:39",
'cfs',
'Inst-Val'
)
# opens a dss file default is version 6
# for a version 7 file pass `version=7` as argument
dssf = phl.hecdss("tseries.dss")
dssf.write(ts_cont)
# * read record *
ret_data = dssf.read(
"/BASIN/LOCATION/FLOW//3HOUR/TEST/",
phl.record_type.TSERIES
)
print(ret_data)
dssf.close()for a detailed documentation visit https://nzahasan.github.io/pyheclib
- add delete record support
- free struct after writing data
- @ write check if data is empty
- tool for record to csv
