Hi,
Does anyone know of a good program to convert Lat/Long to state plane coordinates and vice versa?
I'm hoping to find something for either the HP 35 or for my data collector (Recon with TDS Surveypro).
So far I found these programs:

Has anyone here tried these?
For now, I'll be doing these conversions in class, so I won't have access to a PC or the NGS website. The idea is, I'll do the calcs longhand, then check my answers with the programs.
Thanks for your help!
Happy Easter.

Havent tried these...I'd be curious to see or hear how well they work. Looks like they could be plugged in on a 33 too. Seems like the effort in entering the programs would be greater than the actual use you'd need them for though...
I believe Dr. Bill Hazelton has written many programs, for several of the HP calculators, including the33s & 35s.
Hi Butch,
I agree, hand entering approximately 250 lines of programming might be more hassle than it is worth. If I get some free time later, I'll punch them in and report back on their usefullness.
By the way, I think the programming is a little different for the 33. Bill Hazelton has parallel programs for the 33.

Thanks for the add. links Jeff. What method are you using to do the longhand calcs? The polynomial coefficients method for Lambert projections is a pretty simple method, esp for handheld calculator...but depends on how often you're going to be needing this 'conversion via calculator' I suppose.
Owing to Apple closing down their web hosting services, I've had to move the programs. You can now find them at:
