The elevation of two proposed triangulation stations X and Y, 96 km apart are respectively 123 m and 402 m above sea level. The likely obstruction is situated at Z 56 km from X and has an altitude of 138 m. A. Are X, Y and Z intervisible? Why? B. By how much Y should be raised so that the line of sight may clear Z by 2 meters?
