In trigonometry, the Snellius–Pothenot problem is a problem first described in the context of planar surveying. Given three known points A, B, C, an observer...

In his calculations Snellius made use of a solution for what is now called the Snellius–Pothenot problem. By necessity Snellius's high points were nearly...
