Introduction

This repository includes bash scripts that use Generic Mapping Tools (Wessel et al., 2013) to plot teconic velocities and parameters of strain tensors

License GPL-3.0 Version

main scripts

  1. gpsvelstr.sh : plots velocities and parameters of strain tensor

input files

  1. default-param : default parameters for paths, input files and region configuration
  2. input file for velocities (example test.vel)
  3. input file for strain tensor (test.str)

Documentation

  • Be sure that gmt is installed on your computer
  • Configure file default-param.

If you'd like to use topography, you can download world DEM from here

INPUT FILES

  • input file for velocitiew, use mm for velocities and uncertenties
code lat lon alt vN svN vE svE vU svU
  • input file for straintensor parameters, K in μstrain and Az in degrees
code lat lon Kmax sKmax Kmin sKmin Az sAz E sE gtot sgtot

(do not use a seperator!)

MAIN SCRIPT: gpsvelstr.sh

MAIN OPTIONS

Usage : plot_eq.sh -r west east south north projscale frame| -topo | -o [output] | -jpg

  • r [:= region] region to plot west east south north (default Greece) use: -r west east south north projscale frame
  • mt [:= map title] title map default none use quotes
  • topo [:= topography] use DEM topography
  • faults [:= faults] plot NOA fault database

PLOT VELOCITIES

  • vhor (input_file)[:= horizontal velocities]
  • vver (input_file)[:= vertical velocities]
  • vsc [:=velocity scale] change vElocity scale default (0.05)

PLOT STRAIN TENSOR PARAMETERS

  • str (input file)[:= strains] Plot strain rates
  • strsc [:=strain scale]

OTHER OPRTIONS

  • o [:= output] name of output files
  • l [:=labels] plot labels
  • leg [:=legend] insert legends
  • logo [:=logo] plot logo
  • jpg : convert eps file to jpg
  • h [:= help] help menu

Exit Status: 1 -> help message or error Exit Status: >= 0 -> sucesseful exit

Example:

$ ./gpsvelstr.sh -topo -faults -jpg -logo

Example1

plot velocity test file

$ ./gpsvelstr.sh  -jpg -topo -vhor test.vel -logo

Example 2

plot strain rates from test file

$ ./gpsvelstr.sh -jpg -topo -str test.str -logo

Example 3

Updates

  • 20 Jan 2016: First release gpsvelstr script.
