Extracted text: In a hydrographic survey three stations ABC were established. Stations A and B are on the shoreline and station C is on the sea marked by a buoy. The latitude and departure of the lines are computed as follows: Line Latitude (m) Departure (m) + 159.40 - 326.16 +136.95 +153.82 АВ BC CA +166.75 - 290.77 24.
