How to graph an Oval on a geographical Map

BLUF: I'm trying to graph an oval on a matlab map using something like geoscatter.

I have data for 6 points, each of these points has a latitude and longitude with each of these having a standard deviation (in miles) associated with them.

Also, the standard deviations are in units of miles also.

I may not be explaining it well enough but I am lost on how to proceed here.

Hi Aiden,

As per my understanding, you can use “ellipse1” function to get geographic ellipse from center, semimajor axis and eccentricity. One of the syntaxes is:

 [lat,lon] = ellipse1(lat0,lon0,ellipse)

Using this you can plot the map and the oval using the “geoshow” function.

So, based on the provided parameters, the “ellipse1” function calculates the latitude and the longitude of the oval. Finally, the map and oval are plotted in the same figure using the “geoshow” function.

You may have a look at the following MATLAB documentation pages for reference:

Geographic ellipse from center, semimajor axis, eccentricity, and azimuth - MATLAB ellipse1 (mathworks.com)

Display map latitude and longitude data - MATLAB geoshow (mathworks.com)

I hope the above information will be helpful in resolving your query.

Cheers,
