Does anyone here know a good source that gives details on how to redefine coordinate systems without relying on existing software implementations?

  Snyder is the canonical source that most use. Free download from USGS. Once you see the math you’ll understand why you want to use libraries. https://pubs.er.usgs.gov/publication/pp1395 https://pubs.er.usgs.gov/publication/pp1395

    HA! The upshot of Snyder is that it includes -samples- for everything, which is really useful if you ever wind up having to deal with an Albers Conic over 3 states in the US, that also is using an elipsoid typically used in India. Oh, also it's 2010 and you can't afford actual GIS tools. You have Google Earth, Visual Studio, AutoCAD, and Microstation. Good Luck.
