plotgrav's Introduction

plotGrav

Matlab GUI tool for processing & visualization of various time series.
The toolbox was developed for processing of gravimeter time series but can be used for arbitrary input.

Features

load 4 different data files at once in diverse formats such as TSoft, Campbell Logger, or Dygraphs csv
export & print time series
use scripts (instead of GUI)
compute statistics such as correlation
apply ML methods such as regression or principle component analysis
apply corrections (e.g., steps, gaps)
filter time series
compute spectral analysis
do some algebra on all input series (e.g., add, subtract, divide time series)
download & process Atmacs atmospheric model data
compute polar motion and length of day gravity effect
introduce time shifts and re-sample the data (new temporal resolution)
automatically fill missing data (interpolate or set to constant)
estimate gravimeter calibration parameters
superimpose plots with latest Earthquake records
stack multiple files into one (for gravimeter records)

Usage

Run plotGrav.m or see plotGrav_TestScript.plg for scripting

Dependency

Tested and developed under Matlab R2015b
- Some functions use statistics, curve fitting, and signal processing toolboxes
The GUI appearance depends on Matlab version and screen resolution (optimized for 1920x1080)
