Plotting Points on a Map in MATLAB

Question

I want to plot different locations on a map of NY state. My current code plots the entirety of North America because I couldn\'t find how to plot just one state. I\'m trying

Answer 1

You can get a USA state map with usamap('New York') and plot an overlay text with textm. Here, 25 random points and their label are plotted on the figure.

The following plot

is produced by

latlim = [39 47];
lonlim = [-81 -70];

figure('Color','w');
usamap('New York')
shi = shaperead('usastatehi', 'UseGeoCoords', true,...
            'Selector',{@(name) strcmpi(name,'New York'), 'Name'});
geoshow(shi, 'FaceColor', [0.3 1.0, 0.675])
textm(shi.LabelLat, shi.LabelLon, shi.Name, 'HorizontalAlignment', 'center')

nb_point = 25;
LAT = latlim(1) + (latlim(2)-latlim(1)).*rand(nb_point,1);
LON = lonlim(1) + (lonlim(2)-lonlim(1)).*rand(nb_point,1);
h = geoshow(LAT, LON, 'DisplayType', 'Point', 'Marker', '+', 'Color', 'red');
textm(LAT, LON+0.3, num2str((1:nb_point)'), 'FontSize',14)
