Before revision: 60–67 In surveying In surveying work,Glossary of the Mapping Sciences, American Society of Civil Engineers, page 451. the most common methods of computing the coordinates of a point by (angular ) resection are the Collin's "Q" point method (after John Collins) ) as well as the Cassini's Method (after Giovanni Domenico Cassini) and the Tienstra formula, though the first known solution was given by Willebrord Snellius (see Snellius–Pothenot problem).
