A useful set of Coordinate Geometry tools for surveyors.

This app has been developed in consultation with experienced surveyors and includes many of the common Coordinate Geometry (COGO) calculations needed for field work.

Formulas supported include:

* Traverse / Radiation (2D and 3D)

* Inverse / Join (2D and 3D)

* Intersection by bearings

* Intersection by distances

* Intersection by bearing and distance

* Intersection of two lines

* Intersection of perpendicular lines

* Point Scale Factor

* Grid Convergence

In addition, the app also includes a bearing calculator and a general purpose calculator tool which includes the basic trig functions and a decimal degree to Deg/Min/Sec converter.
