Coordinate transformation Geographic to Proyection
¿ Does anyone knows how to convert Geographical Coordinates (lat and long.) to Gauss-Kruger 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/DOC-6527

Good luck. Please let me know if you need help.

Fred

Dear Fred, TYVM for all the information. The PDF is just excellent.

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.

Thank´s for information. 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?
