Coordinate transformation Geographic to Proyection
¿ Does anyone knows how to convert Geographical Coordinates (lat and long.) to GaussKruger projection or UTM, and vice versa ?. I would like to have a program to do that in my HP 35s

RE: Coordinate transformation Geographic to Proyection
I know how to do lat/long to and from UTM. In December 2014, I wrote a Mathcad Prime 3.0 worksheet to perform these calculations and posted it on the PTC user forums. I included an Adobe Acrobat printout for people without Mathcad. Because Mathcad shows the actual equations (unlike a spreadsheet), you should be able to follow the procedures and create an RPN program. This Mathcad worksheet includes explanatory text throughout the calculations and a list of references.
I have attached a copy of the .zip file that contains both the Mathcad and Acrobat versions. You can also find the same thing here: https://www.ptcusercommunity.com/docs/DOC6527 Good luck. Please let me know if you need help. Fred

I attach a file with numerical examples that fit the map projection system used in Argentina (see details and check the website to develop numerical examples) I await your comments Pedro

Here is the code to do gauss kruger projection in python. It is reasonably well commented. Shouldn't be that difficult to program for HP calc.

Many things to comment, Argentine GK proyection system has some specifics and is very difficult for me understand phyton programming language. Do you know about a webpage that makes the process so I can try some examples?
