I want to mark certain locations (lat and long in a .txt file) on a world map with symbols. I am using the following code.
But I am not getting the desired results. Can you please resolve this issue?
#!/bin/bash
gmt begin world png
gmt coast -Rg -JK180/22c -B45g30 -Gwheat -Slightblue -A1000 -Y7c
gmt plot -C -Sci -Wfaint -hi1 world_1.txt
gmt end
world.txt contains longitude and latitude of marking.
|77.50|8.20|
|83.50|17.20|
|71.50|20.20||
|80.50|20.20|
