another great idea!  thanks Rolita!  this will come in handy!

Thanks for this Rolita!

HI everyone , You can also get a very good computer program at MN dot, call MN level. this program reads, and adjust a comma-delimited file that contains field data for a level run,as output  by Trimble Geomatic's Office .A very good program.

thanks looks interesting, but we teach lower levels and basics will be able to use it for my research though  

HI Rolita ,again. Just thought it might help. I have run  first order levels for the corps of Eng. on the Mississippi  River  The Instrument had a micrometer attached to it and the rods have three faces  you read to the nearest .001 on two sides then the third the same ,then take the micrometer and move the center hair to the nearest .005 between the hundred marks. You may have to move it up or down then read the rod and then read the micrometer. All the shot had to be at the same dist. bs and fs had to match.  I think now they use the metric system because I did a survey on a navy, army base and they told to use metric system to lay out the buildings . I have spent my share of time on the water on rivers and lakes to. Be sure to go to  M N dot site above you there is a lot of  good stuff there a  Level program adjustment.  talk to you later.

HI Rolita, I thought of another site with good downloads and e books, there is a lot good stuff that you can use in  your class just do a search on the site this page is on the HP35s programs i do not know if you use HP RPN  but this link will connect  to the site they have many PDF files and e books to down load free or buy. Also if you use Emulators in class I can help you with that . and set one up with free surveying cogo program, so you can use it, in the  class,. this is the Hp 50g . Have a good Day
