Florence_Track_edit.txt

I'm trying to plot hurricane track data on a map, but I'm not super fluent in Matlab. I have a txt file that I'm loading into the system but the other resources I'm finding don't quite align with what I'm doing.

Edit: I've included the data. And below is a link to the method I tried using to plot.

Well, you don't get anywhere by not trying something! :)

You have date, time, lat, lon...that's all that's needed to plot. Look at readtable as one likely candidate way to import the data file. You'll need to parse the lat, lon data to handle the appended direction, but that's handled easily enough by converting the cellstr() that will be returned by default with str2double() or similar.
Well, it shouldn't take much imagination to stop in the example code after one data set nor to see with only one you don't have to select the data by ID/name.
Try with the "Getting Started" documenation and the "On Ramp" training to get the barest of MATLAB syntax under belt...there's a whole section in the documentation on data import with examples for templates...

Thanks! That was helpful, but I'm still running into an issue. I can see the map, but my data isn't plotting. Here's what I've done so far and my output.

FloTrack = readtable('Florence_Track_edit.txt');
figure
FloTrack.Properties.VariableNames{1} = 'Date';
FloTrack.Properties.VariableNames{2} = 'Time';
FloTrack.Properties.VariableNames{3} = 'Latitude';
FloTrack.Properties.VariableNames{4} = 'Longitude';
FloTrack = removevars(FloTrack, 'Var5');
latFlorence = FloTrack.Latitude;
lonFlorence = FloTrack.Longitude;
geoplot(latFlorence, lonFlorence)
latFlorence = str2double(FloTrack.Latitude);
lonFlorence = str2double(FloTrack.Longitude);
geoplot(latFlorence, lonFlorence)
geolimits([0 50], [10 90])
geolimits([0 50], [-10 -90])
geoplot(latFlorence, lonFlorence, '.-')
geolimits([0 50], [0 90])
geolimits([0 50], [-90 0])
