I have plotted some measurements in the latitude and longitude in which they have been measured. I want to plot a physical map over them. I have tried with geoshow but it doesn't work. Can someone please tell me how can I add a physical map of the region I am studyng over the already plotted data?

Thanks for reading

if true
    for i=1:3
    figure
    f=linspace(0,1,100);
    for j=1:size(EOF,1) 
    m2=max(max(EOF(:,i)));
    mn2=min(min(EOF(:,i)));
    c2=(EOF(j,i)-mn2)/(m2-mn2);
    color2b(j,:)=[0.3*c2 0*c2 (1-c2)];
    lat=coord2(j,1);
    lon=coord2(j,2);
  if EOF(j,i)<0
  plot(lon,lat,'r*','MarkerSize', 0.5)
    a=text(lon,lat,num2str(EOF(j,i),3),'Color','r','Fontsize',abs(EOF(j,i))*30)
    hold on
  else
      plot(lon,lat,'b*','MarkerSize', 0.5)
    a=text(lon,lat,num2str(EOF(j,i),3),'Color','b','Fontsize',abs(EOF(j,i))*30)
    hold on
  end
    hold on
    end
end
  end

Hello my friend. I know it is maybe too late for the answer... but anyway. I'll attach a function for you.

Here is an example of how you should use this... 1) Place the file "rgrd_WorldCstLinePacific.mat" on a folder. 2) Place "world_coast.m" in the same folder 3) in your code write this: just after your plots world_coast(lonmin,lonmax,latmin,latmax,'k') %['k' for black color]

And that's it! :D

If you need other map of the world you can search and download it. They are available in different sites. Anyway you try to use it.

Ex: world_coast(-122,-117,32,35,'k') % this will plot California's coast ;)
