I'm trying to plot positions of earthquakes on a map. The primary goal is to make Matlab plot a map so I can put the positions of earthquakes on it. I've read through the help section for Matlab's Toolbox but to be honest I'm still confused about it. Has anyone used Mapping Toolbox to know how to get a high resolution map loaded into Matlab? So far all I've been able to plot were shape files which only show continents or country borders. I need something more precise.
