Hi guys and girls, I sent this message once before, but I do not think it got through, so I'm reposting.
I know this is slightly off topic, but I ran out of places to ask... I'm looking for a piece of software, it could be a standalone app, or some JavaScript somewhere, that can calculate the 7 parameters of Helmerts transformation from the coordinates of identical points. Lots of applications can transform CRS, even on the fly, but I need something to calculate the parameters... The thing is I'm preparing for an exam, this is like a bar exam so I can get to be a certified surveying engineer, and one of the questions is to calculate the params. A decade ago, when I was a student, I had the formulas in a Sharp programmable calculator (that I borrowed :-)). Alas, both the knowledge, as well as the programmable calculator got lost somewhere over the years :-) --- Zoran Jankovic
