Hello everyone,

I am trying to get positions at the following map with ginput command. But the problem is I want to see the position of the point before clicking it.

Is it possible to that? After I clicked N points I can see positions, but I can not click them anymore. I should see the position first and after that I need to click it.

Thanks in advance!

Here is the code:

clc
clear
close all
geoaxes('Units','normalized');
N=5;
set (gcf, 'WindowButtonMotionFcn', @mouseMove);
for i=1:N
[lat,lon]=ginput(1)
hold on
geolimits('manual')
geoscatter(lat,lon,'filled','b')
end
set (gcf, 'WindowButtonMotionFcn', @mouseMove);
function mouseMove (object, eventdata)
C = get (gcf, 'CurrentPoint');
title(gca, ['(X,Y) = (', num2str(C(1,1)), ', ',num2str(C(1,2)), ')']);
end
