Traverse Calculations Determine Angular Misclosure Balance Angular Misclosure Determine Directions of Sides Latitudes and Departures Determine Linear Misclosure Linear Misclosure. These discrepancies represent the difference on the ground between the position of the point computed from the observations and the known position of the point. The easting and northing misclosures are combined to give the linear misclosure of the traverse, where linear misclosure = ( E. 2 + N. 2) E LINEAR ERROR OF CLOSURE.— In practice, as you will learn, the sum of the north latitudes usually differs from the sum of the south latitudes. The difference is called the error of closure in latitude. Similarly, the sum of the east departures usually differs from the sum of the west departures Step 4: Linear Misclosure and Relative Precision Example 10-3 (textbook). If all angles and distances were measured perfectly, the algebraic sum of the departures of all lines in the traverse should equal zero. Likewise, the algebraic sum of all latitudes should equal zero.! C x =#X C y =#Y where: C x = total closure distance of X C y = total.

Traverse Linear Misclosure and Relative Precision For a closed traverse, it can be reasoned that if all angles and distances were measured perfectly, the algebraic sum of the departures of all lines in the traverse should equal zero. Likewise, the algebraic sum of all latitudes should equal zero. Unfortunately eve Fractional Linear Misclosure (FLM) = 1 in *D / e **9172.59 = 1 in (9172.59 / 0.661) = 1 in 13500 [To the nearest 500 lower value] Acceptable FLM values :-•1 in 5000 for most engineering surveys •1 in 10000 for control for large projects •1 in 20000 for major works and monitoring for structural deformation etc

Linear misclosure is the hypotenuse of a right triangle whose sides are the misclosure in latitude and the misclosure in departure. What is the purpose of traversing? Theodolite traversing is a method of establishing control points, their position being determined by measuring the distances between the traverse stations (which serve as control. If the linear misclosure is acceptable, then this can be adjusted out of the network, but if the misclosure is too large then the fieldwork should be repeated (unless the source of the problem can be isolated). 25 linear misclosure In above example can be calculated as follow . 26. e v (?

In this next section I start to work with equations that are fractions. I first start with some basic ones consisting of two terms, one of which is a fraction. I continue to look at fractional equations consisting of one term which is a fraction but in the denominator of that fraction ther The linear measurements can be performed by any of the methods listed in the horizontal method. For ordinary surveying, chaining is perhaps the most common. The direction of the lines can be measured by the techniques discussed in Compass surveying and Theodolite.

My angle misclosure was 3.5 and linear misclosure was 0.02 (about 1:90,000). I was completely satisfied with those results. Due to the shape of the project, obstructions (mainly a 10ft high wood fence around the perimeter of the project), and the location of points that I had to traverse through, I ended up with 2 small angles in my traverse.
