In surveying it is in reference to a system of point who's beginning was also it's end.all the sums could be adjusted for a better fit. This is a Closed Traverse. A Traverse Line does not work like this. It's corrections or only averages of each part if this is applied to the survey.There maybe cases were only one angle and one distance is taken at each leg of this Line.This is wrong. Multiples must be taken in this system . This is also to make sure these were correct. Many times i have had to explain to someone your traverse line is not a traverse. Traverse Lines has stations ,a Traverse does not, a traverse can be adjusted, a traverse Line can not. A compound traverse is two traverse lines that have been tied together . This does not make them a Traverse. IN a old survey book of mine it says a traverse is a series of points that are connected by angles and distance and can be seen from one point to the next and to the next until they connect back to the first point. This allows the surveyor to make polar or rectangular adjustments to this system .</p><p></p><p>Can be seen? That's the only way you would turn the the angles and measure them fiscally . Why he said this i do not know, but that is the only way. So how does GPS " Traverse" fit into all of this . and is it really a traverse or is it only a system of Control points. Voice your conception of what you think and how this terminology is applied. so what makes a Traverse and a Traverse Line no matter what you use.</p><p>billy</p></div>Double rodding, I never called it this, I used Double turns, 2 of somethinghttps://landsurveyorsunited.com/hubs/kickassformulas/forum/double-rodding-i-never-called-it-this-i-used-double-turns-2-of2016-03-13T08:55:00.000Z2016-03-13T08:55:00.000ZBilly Brookshttps://landsurveyorsunited.com/surveyors/BillyBrooks<div><p><a target="_self" href="http://landsurveyorsunited.com/group/kickassformulas"><img class="align-right" src="{{#staticFileLink}}1200695098,original{{/staticFileLink}}" width="380"/></a>Hello Eveyone, I guess it does not matter what you call it ,if it can be mastered it saves time and money.</p><p></p><p>Running long level runs can take a lot of time., To insure they are correct they must be ran into a level loop. Sometimes bench loops are a costly procedure.Bench mark are not always close to the job. It also depend on what these elevation are used for and who is requiring them . What order and class they will fall into. lets just say these are third order , three wire. To save money and insure that they are correct, try the <em><strong>double rodding</strong></em> or double turns method .Whatever you call it. First you will need two good turns this can be metal pikes or long screwdrivers to use as turning points and of course a small hammer. You can use two rodmen or one good rodman . Level rod or rods and a rod bubble for each rod. First you will start at the BM ,most of the time there will be only one, if you do have two thats great ,if not you will have to make one more. so first do that make a TBM close to the BM and loop between them. Now you are ready to start you double rodding loop. also try to balance you shot on BS and FS distances . Have the rodman to pace his steps.Now here is the next trick have the rodman to set one turn higher or lower than the other turn and kept this shot order the same. If the turn on his right is first and higher keep it in this order. We will call it " A " because you will shoot this turn first and the lower on the left it will be " B ". So come off your BM and TBM called the BM A and the TBM B have the rodman set TP A and TP B shoot A and shoot B, now your ready to pick up and move to the next setup .Set the level up at the balance distance and shoot TP A record it , the same for TP B and move you rod man ahead and set TP A and TP B again shoot TP A and TP B, Remember what I said about High and low because this will help you not to make a mistake on what turns you are shooting also the one on the right first then the one on the left next,and by looking at the elevations you will know which is which. Repeat this until you reach your new BM site as before set a BM and a TBM. Because now you will set the BM A 2 and the TBM B 2 then tie between them to close the loop. If you do not set, but only one, then there will only be one shot to the one BM off of the two HI's this will not prove your last shot was a closer.You must tie between these two to make the loop. By learning how to do this method you will only have to walk this long distance one time, if not you will walk it twice. and twice the time.The notes can be kept together or in two different books or on two different clip boards. Whatever you decide and like. This method can be found in many survey manual.</p><p></p><p>BIlly</p><p></p><p><a rel="nofollow" href="http://engineeringtraining.tpub.com/14069/css/14069_486.htm">http://engineeringtraining.tpub.com/14069/css/14069_486.htm</a></p></div>L.

But wait it was, sewer on one street a storm sewer on the next and grade had to be set on a drainage ditch. It was one of those jobs that was taken so soon ,like here are the plans ,he has equipment waiting on YOU. In my day and time this was no big deal I wasn't brought in the day of Auto Cadd so this wasn't no dog and pony show to me. I had seen this movie many times. Now I had a new I Man that thought he was smarter than the average bear , then what comes out of he mouth as he picks up my HP 32s calculator, which he had never seen before. What does this key do.? Of course I asked what key ? He then said the one with L R above it . My answer , everything you will do today . He said this little key. I said YEP!!</p><p>So then began his lessons on HP calculators and Linear Regression.

</div>Rules of Thumb for surveyinghttps://landsurveyorsunited.com/hubs/kickassformulas/forum/rules-of-thumb-for-surveying2015-10-12T01:50:48.000Z2015-10-12T01:50:48.000ZMichael Alan Sanchezhttps://landsurveyorsunited.com/surveyors/MichaelAlanSanchez<div><p>Several rules of thumb which makes life a little easier:</p><p>When checking in and your off 30" remember</p><p>20" is 0.01' in 100' so if your 50' feet away from your backsite for a topo you are less then a hun. and good!</p><p></p><p>Steel expands 0.01' per 100' per 15 degrees of temp. (not use so much anymore, but handy when working with bridges, steel trusses, etc.</p><p></p><p>PPM's are parts per million, so if you have 100 ppm's it is still 1:10.000, still plenty accurate for most work.</p><p>So if you need a quick scale factor or proration for your job, set your PPM till you hit record on your base line, it is handy when laying out grid lines around a building whose envelope corners you have already staked. </p><p></p><p>Remember that Iron leans from the Sun, so get your grid line up early. Also keep your benchmarks on the darkside of the building or in shafts. If you hold about 10 lbs, enough get kinks out of your chain, and acclimatize the building, you should get consistent and correct benchmarks on upper floors.</p><p></p><p>Remember everything settles, This could add up to a big extra instead of a backcharge, look as the soils or geology report for settlement criteria.</p><p></p><p>I always remember that the "the sine times the slope = the elevation" or "the tangent times the tape (flat read) equals the elevation" of course that leaves cosine the relation between the two adjacent.</p><p></p><p>Remember in Autocad or any other program "80% of the time you use the same 20 commands" "80/20 rule. Also 80% of the work is done by 20% of the people. etc.</p><p></p><p>And "always, always, always back up data" better to copy not move, ex. keep raw files in data collector as long as possible.</p></div>How to Square Any Two-Digit Number In Your Headhttps://landsurveyorsunited.com/hubs/kickassformulas/forum/how-to-square-any-two-digit-number-in-your-head2012-12-20T23:44:48.000Z2012-12-20T23:44:48.000Z⚡Survenator⌁https://landsurveyorsunited.com/surveyors/Survenator<div><p>Land surveyors are constantly crunching numbers in their head.  But if you are like me, math is "work" part of surveying.</p>
<h2>Square Any Two-Digit Number In Your Head</h2>
<p>To square any two-digit number X, decide what number N it will take to raise or lower X to P, the nearest multiple of 10. Add the opposite of N to X to get Q, multiply P times Q, and add N^2 to the result. For instance:</p>
<blockquote>
<pre>67 * 67 = (67 + 3) * (67 - 3) + (3 * 3) = 70 * 64 + 9 = 4489</pre></blockquote>
<p>The hard part is 70 * 64, but if you teach yourself to ignore the zero at the end of the 70 and multiply from left to right, it sounds like this:</p>
<p>"Seven sixes make forty-two, times ten makes four hundred and twenty. Seven fours make twenty-eight, plus four hundred and twenty makes four hundred and forty-eight, times ten makes forty-four hundred and eighty, plus three squared--that's nine--makes forty-four hundred and eighty-nine."</p>
<p> </p>
<p>Presto, you've figured out the answer in less time than it takes to say it. Note: don't be discouraged if you forget what number you needed to add at the end, or what number you were originally squaring; they're going to drop out of your short-term memory storage until you practice enough.</p>
<p> </p>
<p>Here's an easier one, 52 * 52:</p>
<blockquote>
<pre>52 * 52 = (52 + 2) * (52 - 2) + (2 * 2) = 54 * 50 + 4 = 2704</pre></blockquote>
<p>Numbers ending in 4 and 6 are the hardest, because you've got to add 16.</p>
<blockquote>
<pre>86 * 86 = (86 + 4) * (86 - 4) + (4 * 4) = 90 * 82 + 16 = 7396</pre></blockquote>
<p>Numbers ending in 1 are easy:</p>
<blockquote>
<pre>71 * 71 = (71 + 1) * (71 - 1) + (1 * 1) = 72 * 70 + 1 = 5041</pre></blockquote>
<p>... and numbers ending in 5 are trivial:</p>
<blockquote>
<pre>45 * 45 = (45 + 5) * (45 - 5) + (5 * 5) = 50 * 40 + 25 = 2025</pre></blockquote>
<p>This is math that the average fourth-grader can handle ... can you?  </p>

<p> </p>
<p>This is direction sheets and traverse sheet calculations made easy for 1st year students. I realy hope that it will help you.</p>
<p>You 1st have to reduce your fieldbook, then calculate your direction sheet and from there calculate your traverse.</p>
<p>why do you do this ??? so that you can calculate the coordinates of your unknown points using a traverse method.</p>
<p>enjoy</p>

<span><span>The formula: </span></span><br />
<span><span>D = ((ba-bb) -100) * (sin V) ^ 2</span></span><br />
<br />
<span><span>S = ((ba-bb) -100) * sin V</span></span><br />
<span><span>△ H = tan (90-V) * D + IH-TH</span></span><br />
<span><span>Coordinate</span></span><br />
<br />
<span><span>Kor.X = SIN AZ * D + X ST</span></span><br />
<br />
<span><span>Kor.Y = COS AZ * D + Y ST </span></span><br />
<br />
<span><span>EL .= △ H + EL ST where the vertical angle V = AZ = Azimuth ST = Station tool tool TH IH = high high = target / beacon meters</span></span></span></p>
