MATLAB: How to get the points of [lat, lon] of a full great circle

gcwayptsgreat circlelatitudelongitudemap

the matlab function gcwaypts generates points on the short arc of the great circle across two given points.

How to get the full great circle?

Best Answer

I would use a combination of azimuth, gc2sc, and scircle1:

az = azimuth(lat1, lon1, lat2, lon2)
[lat, lon, r] = gc2sc(lat1, lon1, az)
[latc, lonc] = scircle1(lat, lon, r)

MATLAB: Writing multiple Lat, lon points to KML File !

The syntax for kmlwrite is:

kmlwriteline(filename,latitude,longitude,altitude);

The fourth variable passed is considered as altitude data. In your case you can create an array with multiple lat and lon points and send that array to the function.

Try this:

lat_points = [lat1;lat2;lat3;lat4];
lon_points = [lon1;lon2;lon3;lon4];
kmlwriteline(filename,lat_points,lon_points);

Hope this helps.

MATLAB: Generating large circles using scircle

I don't think scircle2 wants x or y values, it wants lats and lons. I wrote a circlem function that streamlines the process of plotting circles of a given radius on a map. Perhaps that is what you're looking for?
