The Gauss projection is one common methods for projection transformation. The Gauss projection is The theory and method to calculate the rectangle coordinate related geographic coordinate, on the contrary, the Gauss inverse projection is to calculate the geographic related rectangle coordinate. In this problem, Bf is an important parameter. If Bf is explicit, the process of the Gauss inverse projection will become simple. So to some extent, the key of the Gauss inverse projection is to calculate the value of the parameter Bf. The paper put forward a method for the Gauss inverse projection, which firstly uses iteration method to solving the value of the Bf, and then uses the value to inverse the Gaussian coordinate. It is suggested, through writing programming language, that this method, versus to regular ones, is easier, quickly and have a high precision, so it is practical.
