You can use “camtargm()” functions to set the camera target using geographic coordinates. For further information refer to the documentation on camtargm().
tlat = -30;
tlon = -70;
camtargm(tlat,tlon,0);
%Return the camera target in projected Cartesian coordinate system
[x,y,z] = camtargm(tlat,tlong,0);
To set the camera position use “camposm()” function to set the camera position using the geographic coordinates. For further information refer to the documentation on camposm()
plat = -50;
plon = 160;
camposm(plat,plon,1);
%Return the camera position in projected Cartesian coordinate system
[x,y,z] = camposm(plat,plong,1);
