How about:

struct place {
  char nameOfPoint[25];
  float latitude;
  float longitude;
  int directionOfTRavel;
};

place places[50];

//To write :
places[3].nameOfPoint = "Camera 1";
places[3].latitude = -33.951918;
places[3].longitude = 22.426744;
places[3].directionOfTravel = 50;

Try to avoid Strings with Arduino... They just call for trouble.
