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);
Refer the following documentation link for more details on “text”:
