rawdatx 0.1

Installation

The following prerequisites need to be installed:

• Python 2.7, 3.4, or 3.5

• numpy 1.9 or higher

• xlsxwriter

optionally (recommended):

• lxml

• asteval

The easiest way to install rawdatx is through pip: pip install rawdatx

Alternatively, download the latest version from the repository https://github.com/cpetrich/rawdatx and install with python setup.py install.

Usage

To convert a TOA5 file to XLSX, run the following script:

import rawdatx.read_TOA5 as read_raw_data
import rawdatx.process_XML as process_XML

config = './config.cfg'
read_raw_data.main(config)
process_XML.main(config)

Input and output files are specified in an UTF-8 encoded configuration file config.cfg:

[RawData]
raw_data_path       = ./raw-data/
mask                = CR1000_*.dat
logger_time_zone    = UTC+1

[Metadata]
Project      = My project name

[Files]
xml_map_path        = ./
xml_map             = data_map.xml
data_path           = ./
processed_data_xlsx = processed_data.xlsx
xml_dtd_out         = data_map.dtd
raw_data            = consolidated_raw_data.npy
processed_data_npy  = processed_data.npy

The [RawData] section specifies the location of the logger input files, the [Metadata] section defines metadata entries copied into the XLSX file, and the [Files] section specifies path and file names of output and intermediate files (data_path) and input XML Definition File (xml_map_path and xml_map).

The XML Definition File (data_map.xml) may look like this:

<?xml version="1.0" encoding="UTF-8" ?>
<measurements from="2015/05/03 11:45">
    <group name="Logger">
        <map name="Battery Voltage" unit="V" src="Batt_V" />
        <map name="Internal Temperature" unit="°C" src="T_panel" />
    </group>
    <group name="Weather">
        <map name="Air Temperature" unit="°C" src="T_air" />
        <map name="Relative Humidity" unit="%" src="RH" />
        <map name="Wind Speed" unit="m/s" src="Wind_speed" />
        <map name="Wind Direction" unit="°" src="Wind_direction" />
    </group>
</measurements>
