How to plot multiple fault segments on a map

Q&A

Dear All GMT users,

I have a TXT file of several faults in this form:

33.339584635128 28.617986261144
33.336784875459 28.571327559585
33.334689294277 28.557183318211

33.564389220623 23.587404965303
33.587382988442 23.558727612818

33.598855626283 23.543696754818
33.619689765607 23.526132751617

33.514591687908 23.584902420971
33.52811721346 23.555073703787
etc…

And I use this command line:

gmt psxy faults.txt -R -JM -Sf0.3/10p+r -W1,red -O -K -V >> ps

However nothing appears. But when I separate them in several files, they appear, like that:

gmt psxy faults_01.txt -R -JM -Sf0.3/10p+r -W1,red -O -K -V >> ps
gmt psxy faults_02.txt -R -JM -Sf0.3/10p+r -W1,red -O -K -V >> ps
gmt psxy faults_03.txt -R -JM -Sf0.3/10p+r -W1,red -O -K -V >> ps
etc…

How can one plot all faults using only one command? by the way the number of faults that exceed 100 faults, therefore repeating psxy command is not a smart solution :frowning:

Many thanks in advance for any help.

Have you try to add a “>” between segments?

Does this still apply when working with GMT version 6.6.0? If not, what could be the alternative?

It should work in GMT 6.6.

If there are problems setting up the file or handling the segments correctly, an alternative would be to store the data in a shapefile and plot it from there.
