hello

i have plot india's map using 'worldmap' … i am geting latitude longitude grid with 10 lat/long spacing. Please let me know how can i get the 1 degree spacing of latitude and longitude????

thanks in advance….

To change the default meridian and parallel spacing after creating a map axes with worldmap, set the MLineLocation and PLineLocation properties using setm. The following sets the spacing to 1 degree:

setm(gca,'MLineLocation',1,'PLineLocation',1)

Use doc('axesm') to bring up the axesm reference page and learn more about these and other map axes properties.

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)

To adjust the spacing between the latitude and longitude lines of your grid, set the MLineLocation (Meridians) and PLineLocation (Parallels) properties of your grid appropriately. You may use the following code:

gridm('on');
gridm('mlinelocation',2,'plinelocation',2)

to set a spacing of 2 degrees each between the meridians and parallels respectively.
