TRDI ADCP Work Horse (wh) Reader

Overview

Reads data from TRDI ADCP work horse data loggers.

Contains methods to convert from PD15 to PD0. Once in PD0, the data can be parsed into a Python dictionary.

Sample Output

Installation

git clone git://github.com/USF-COT/trdi_adcp_readers.git
sudo python setup.py install

Test

From the root directory run tests.py to test against a known PD0 and PD15 file

python tests.py

Example

Parse PD0 Data File

from trdi_adcp_readers.pd0.pd0_parser import parse_pd0_bytearray
pd0 = ''
with open(<path to PD0 file>, 'rb') as f:
    pd0 = f.read()
pd0_bytes = bytearray(pd0)
data = parse_pd0_bytearray(pd0_bytes)

Parse PD15 Data File

from trdi_adcp_readers.pd15.pd0_converters import PD15_file_to_PD0
from trdi_adcp_readers.pd0.pd0_parser import parse_pd0_bytearray
pd0 = PD15_file_to_PD0('./140B97C6', header_lines=2)
data = parse_pd0_bytearray(pd0)

Note that this example uses the included file 140B97C6. This file is a test GOES file transmitted by an in-shore COMPS station. This station is located in a shallow area. Only data from the first few cells is valid. Transmissions from this station include a GOES header and an empty line before the PD15 data. The PD15 converter skips these first two lines using the argument header_lines=2.
