horizontal curve pgm. for surveyors Message #1 Posted by john on 17 Mar 1999, 10:51 p.m. this message pertains to state highway department engineers who survey horizontal curves on a regular basis. I have written a program on the 41, 42s, and 48 (all the same program) which, given 3 pieces of data, will calculate an entire simple curve for the purpose of laying in from the PC (BS on PI or back tangent) with a total station. This program can save 45 min. or so key punching. The only catch is that you have to have the IR printer. If anyone is interested, please let me know and I will ask the most honorable webmaster to post it. Any takers? thank you, john

Re: horizontal curve pgm. for surveyors Message #2 Posted by dave PLS on 18 Mar 1999, 3:42 a.m., in response to message #1 by john I say go for it! Sounds like a very useful program for the likes of us. Besides, look at the number of "survey pac" wanted ads posted in regard to our beloved companion the 41. Now, get to work on the vertical curve design and then you really got something. Yep, us surveyors do more than look through the "thingy", when were not you can probably find us with a set of plans on a suburban hood punching away on an hp.

Re: horizontal curve pgm. for surveyors Message #4 Posted by Steve Strapac on 23 Mar 1999, 12:05 a.m., in response to message #3 by john Have you checked out www.hpcalc.org? It is "Mecca" for the HP 48 series. There are hundreds of programs, and dozens of engineering programs, including several Surveying programs. I posted a large zip file that contained several progams written by Victor Maletic, Caltrans Bridge Engineer. One is "traverse", its function obvious. Another is referred to as "heck-uva-deck" it is a powerful survey program used for surveying/laying out bridge decks. It is useful for ground surveying as well. The site is run by Eric Rechlin(?)

Re: horizontal curve pgm. for surveyors Message #6 Posted by SHAWN ATHERTON on 27 Mar 1999, 11:15 a.m., in response to message #5 by john I have written what i thought was the complete and most efficient horizontal curve pgm. for the HP 42S, hopefully we can talk.
