Joseph,

I work for a State DOT in the ROW Mapping and Survey units.  I was doing one of my occasional searches for someone that may be possibly developing the next generation Coordinate Geometry software.  This link popped up.  I have a running conversation in my e-mail with a west coast CAD trainer where we are teasing each other about just this topic.  He saw something demoed long ago and I would not leave him alone about it.  Bohanna Houston supposedly wrote another cogo package I have not seen and Colorado DOT has there own product available for download with a user doc .pdf.  I have not loaded or looked at yet.  My shop is currently Bentley MicroStation, InRoads, ISurvey, CogoWorks, Leica VivaWorks, ...etc.  I was here when Cad first came in the door and now have just over 30 years in.

We have used CLM Cogo, Charles L Miller's baby, for a long time...late 80s to early 90s start.  It eventually was shelved do to OS issues.  We still have his book you mention, orig manuals and software CDs.  I'm not sure if the hardware locks are in a box somewhere or not.  MIT had a great Prof those years!!  My dad just missed Charlie's materials being through Northeastern U civil co-op program by then.

If you write an updated version of Charlie's masterpiece you will have the civil engineering customers beating a path to your door.  Anyone with over 15 years in any firm/agency knows the CLM name and the cogo.  There has been no suitable replacement to date....none.

I wish you all the best in your quest and if I can be of any assistance with old materials I'll try to do my best without costing me my ride.  I'm not sure if it can be considered open source now or not.

God Speed......God Speed.

ps.  I'm a crunchbang linux user at home which came with LibreOffce rolled in.  Great app.  Linux rocks.  Some of my past cad system management duties using red hat then made the switch easy.
