I'm using an application that uses equations from USGS Bulletin 1532 (see source code - line 295: http://docs.ros.org/en/kinetic/api/robot_localization/html/api/navsat__conversions_8h_source.html#l00295). However, I need to use proj4 to do coordinates conversions. So I need to convert from one given projection to the projection used in the equations from USGS Bulletin 1532.
I'm using the C# package DotSpatial.Projections (which is a port for the popular proj4 C++ library to C#). To convert from one coordinate system to another, it receives a proj4 string, such as "+title=WGS 84 (long/lat) +lat_0=0 +lon_0=0 +proj=longlat +ellps=WGS84 +datum=WGS84 +units=degrees". However I don't know how to determine this string for the case of the USGS Bulletin 1532.
How would I define the proj4 string of the equations from USGS Bulletin 1532?
