Comprehensive Analysis and Plotting Tools for Geospatial Time Series Data

This set of programs allows for the analysis and plotting of time series data, including velocity fields and statistics, through various utilities. From generating time series to extracting station coordinates and creating postscript plots, the tools offer a range of functionalities for geospatial data analysis.

  1. Plotting and Analysis Programs Time series Velocity fields Statistics File utilities

  2. Generating Time Series • Glred produces a single file containing position estimates for each day • Script sh_plotcrd extracts position estmates from this file and uses GMT to produces a postscript time series for each site • Sh_plotcrd invokes programs ensum and multibase, and script sh_baseline which produce intermediatefiles • With sh_glred, the glred outputs are separate files but the intermediate files are the same GAMIT/GLOBK Tutorial 11

  3. sh_plotcrd • sh_plotcrd reads an input solution file and plots the times series with GMT. Basic format is sh_plotcrd –s <span> -f <files> where <span> is ‘long’ or ‘short’ to control whether x-axis is days or years, and whether velocities are removed • Output is postscript files with names of the form psbase.<site> (North, East, Up components are all on the one plot). • Other options available GAMIT/GLOBK Tutorial 11

  4. Ensum input and files • ensum is used to extract station coordinates from the repeatability runs • ensum <options> <summary_file> <values_values> <Input solution files ..> • options: Main option is the minimum number of values to be used in computing RMS (for repeatability this is 2) • Summary file is name of file which contains a summary of the repeatability by site and component (NEU) • Values file is the actual time series of results • Input solution files is a list of .org or .prt files or values files from previous runs (must start with va) GAMIT/GLOBK Tutorial 11

  5. multibase • multibase extracts individual time series from a values files and generates a series of files for individual sites and components of the form mb_<site>.dat[123] where 1 is North, 2 is East and 3 is Up • Time can be in day-of-year or years depending on how long the time series is GAMIT/GLOBK Tutorial 11

  6. sh_baseline • sh_baseline plots the times series with GMT and generates postscript files with names of the form psbase.<site> (North, East, Up components are all on the one plot). • sh_baseline -help gives all the options GAMIT/GLOBK Tutorial 11

  7. Velocity plots • sh_plotvel extracts velocities from a prt/org file and creates GMT plots sh_plotvel –f <file> -s <site> where <file> is a glorb prt/org file and <site> is a reference site (optional) • Many other options to customize plots GAMIT/GLOBK Tutorial 11
