The package consists of three directories: Data, Scripts and Figures.
1linearPlots.sh: Contains commands for making basemap for linear projections including the log-log plot. It also explains how to add title, xlabel, ylabel, tick-marks, background-color to the plot.
2PlottingMaps.sh: This explains how to plot the Mercator projection, Alber's projection, Orthographic projection, Eckert projection.
3PlottingLinesSymbols.sh: This script explains the use of
psxycommand to plot the lines and symbols. It also contains the commands to plot the earthquake epicenter with colors representing depths and symbol size representing magnitude.
4PlottingTexts.sh: This script explains how to type texts onto the plots. The user can even type mathematical equations.
5Plottingcontours.sh: This bash script explains how to plot the contour lines using the command
grdcontour. It also explains how to cut the large data set using the
grdcutcommand and obtain the information about it using the
grdinfo. It also explains how to do interpolation of data (nearest neighbour and spline).
6Manipulating_Images.sh: It contains the description of how to make the cpt files, and plot the colorbars using
psscalecommand. It also explains plotting the relief data.
7multiD_maps.sh: This script explains how to plot the multidimensional netcdf data in GMT.
8three-DPlots.sh: It includes how to plot the data as 3D plots using two methods: mesh plot, color-coded surface.
