Dear friend
I have a data file with 3 columns as 1 column is longitude, 2 column is latitude and column 3 is values. I want to draw a figure which I attached. I tried with 'scatter' and 'pcolor' but I didn't succeed. I attached a figure as a example and a data file. I hope someone can help me.

You can adjust your plot as needed.
data = webread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1332705/tec.txt');
numericdata = str2num(data);
longitude = numericdata(:,1);
latitude = numericdata(:,2);
color = numericdata(:,3);
geoscatter(latitude,longitude,color,color,'filled')
colormap('turbo')
colorbar

Dear Cameron
Thanks for your replying. I run your code but it inform a error (I sent a figure in the attachements). I use matlab 2016a, It does not have 'geoscatter'. I coppy 'geoscatter' in another verision of matlab. Can you check to help me?

All of the geoaxes plots I'm aware of are only available in R2017b and later releases. If possible, I would try to update to a more recent version as there have been 14 major releases since R2016a.
