Missing local cartesian branch code?

[ffgamelife]

The received GPS message is only converted to UTM coordinates. Should the code for local Cartesian coordinate conversion be added?

robot_localization/src/navsat_transform.cpp

Lines 626 to 636 in ea976f9

	double cartesian_x = 0;
	double cartesian_y = 0;
	std::string cartesian_zone_tmp;
	navsat_conversions::LLtoUTM(
	msg->latitude,
	msg->longitude,
	cartesian_y,
	cartesian_x,
	cartesian_zone_tmp);
	latest_cartesian_pose_.setOrigin(tf2::Vector3(cartesian_x, cartesian_y, msg->altitude));
	latest_cartesian_covariance_.setZero();
