Tartalomjegyzék
GENERAL INFORMATION The symbols used in this Annual are as follows: "0" point zero of the water-gauge NV ▲ warning referring to the fact that the zero point of water-gauge has been changed since the year 1931. [NVj /Orsz. / altitude level in relation to the basic surface of the national network of geo- detical survey /the reference point of this network is identical to the main point of the one-time military survey network at Nadap/.
