The usual procedure for determining the number of condition‐equations in the adjustment of a triangulation‐net is to build up the figure point by point. This method will give the number of angle and side equations, then azimuth, length, latitude, and longitude equations are added to obtain the total number [see 1 of “References” at end of paper”.In a complicated net, it is advisable to have a check on the total number of equations involved. The total number is given by the formula N = V − 3Sn+ Suin which N is the total number of equations, V is the total number of observed directions excluding those on lines fixed by previous adjustment, Snis the total number of new stations, and Suis the total number of unoccupied new stations. This formula is based on the fact that two lines determine a new point and each additional line to this point from established points adds, two equations if the line is observed in both directions or one equation if the line is observed in on
