geosea 2022.1.2.3

A processing package for seafloor geodesy

Project Description

Geosea is an open tool box for seafloor geodetic data processing of dircet-path ranging. It supplies a variety of functions to process acoustic baselines and analyze ground movement.

Dependencies

sciPy: miscellaneous statistical functions

matplotlib: for plotting

pandas: data structures and data analysis tool

numPy: 1.7.1 or higher

obspy: for date and time types

Import of GeoSEA Module

import geosea

Functions

Read raw csw files into an pandas DataFrame:

geosea.read(sal=None ,phi=None, starttime=None, endtime=None, pathname=None, writefile=True, writevariable=True, dateformat=None)

Calculates the sound velocity from temperature in °C, pressure in kPa and constant salinity in PSU.

Complete Baseline processing of horizontal and vertical changes in time:

geosea.bsl(ID=None, st_series=None, bsl_series=None, outlier_flag=False, pathname=None, starttime=None, endtime=None, writefile=True, dateformat=None)

Parameters: SAL constant salinity value in PSU phi Latitude for Leroy formular in XX.X°
pathname Pathname of raw CSV Data files outlier_flag Cuts outlier mesurements automatically (Default = None) writefile Save output data to csv data format (Defulat = True) dateformat GMT_DATEFORMAT or MATLAB_DATEFORMAT
