I made a geoscatter plot using the following code:

geoscatter(Lat,Long,'r', 'filled')

Lat and Long are numerical vectors. My matrix has another column with SiteLabels. How do I assign each dot on my geoscatter plot a Label?

You can apply different data labels to each point on “geoscatter” plot by using the “text” command. The command “text” takes the plot data as input. Following is a sample code:

% geoscatter plot 
lon = (-170:10:170); 
lat = 50 * cosd(3*lon); 
A = 101 + 100*(sind(2*lon)); 
C = cosd(4*lon); 
geoscatter(lat,lon,A,C,'^') 
% label 
a = [1:35]';  
b = num2str(a); c = cellstr(b); % strings to label 
dx = 0.1; dy = 0.1; % displacement so the text does not overlay the data points 
text(lat+dx, lon+dy, c);
