I think your client has an overactive imagination. If he really needed escape routes he wouldn't be telling everyone around about them.

150 meters (490+ ft) isn't too bad a distance, but centering will be critical to keep the angle error to less than your error in the solars. I calcul...

And do you add the errors directly or do you do sqrt sum of squares? That answer will depend on whether the errors are directly related or statistall...

I still need to get the LDP convergence angle equattions added so I can keep the Polaris sights in the adjustment. There are few distance measurement...

You can add my picture from a while back of one I drove past.

Thanks for the pictures. I always like pictures of the people who post.

I figured if you are doing astro measurements you wanted geodetic azimuths. Using the SPC coordinates from the data sheets, I get SPC grid azimuths 17...

Did I type something wrong into INVERSE or is the distance really 842.7767 meters (on ellipsoid) or 0.52 mile instead of 0.47 mile? About 2 or 3 cm l...

You are quite lucky to have two good points close to you. Most people don't. I think the values given are +/- and not the arcs shown in your figure....

Welcome. Are you the Kimberly who was taking pictures at the Surveyors Historical Society event in Philadelphia?

I have no idea what that may be. It's easier to link your photo from your geocaching log than to deal with the overhead of services like photobucket.

The patent text mentions the flutes in connection with stiffness against flexing. I don't see that as a big deal - it would be stronger than a cylindr...
