Options The Options button offers the possibility of editing the Tolerance of the subloops. One may edit a value of between 0.0 and 25.0. (See “Calculations and Compensations” section). These values make it possible for the software to interpret or not interpret a partial point as a subloop. For example, if we assign a 0.0 value, it will not read subloops at the closure, whereas if we assign 25, it will recognize partial points with a margin that is 25 times the Kilometric error of the distance of the subloop. By default, a value of 2.5 is assigned.

It also makes it possible to change measurement units. The units available are Meters, International Feet and U.S. Survey Feet. The equivalence with the meter is as follows: 1 Meter (m) = 3.280839895 International Feet (ift) = 3.2808333333357 U.S. Survey Feet. The change of Units allows one to display the data in the units selected. Likewise, we can export the output formats in the units we have assigned except for the DiNI M5 format. You can select the number of decimal places you want to view: 3 or 4. You can also select whether you want to enter the temperature in degrees Celsius or Fahrenheit.

Recommendations

• It is advisable to use a fixed-height Trimble-brand surveying rod to fix its height along with a small tripod for establishing the rod verticality

• Similarly, we recommend a rod height close to 2-2.5 meters with both Backsight and Foresight without any variation. At 2-2.5 meters, you can avoid level obstacles and establish a parallel of the terrain to reduce the effects of refraction.

• The best practice is to use the same rod for both backsight and foresight. • If two rods are used, it is important to carry out an even number of levelings so that the rod

placed on the starting point is the same as when the line or leveling loop is closed so as to avoid a possible “talon de mira” (staff difference) error.

• It is important to carry out leveling with equidistant sights so as to compensate for refraction and sphericity effects between the Backsight and the Foresight.

• Before starting work, it is advisable to study your route, identify the leveling points and make a sketch of the location of the bases.

• The measurement stations should be established between 50m and 100m away with angles not exceeding 15 º.

• To carry out high-accuracy jobs, it is advisable to take a set of 5 or more readings of a same point in both Direct and Reverse Circle.

31


Calculations and Compensation

• SETTOP Level Me has no limitations with regards to distances and number of levels. Likewise, it can carry out levelings in which the program will automatically recognize identical points and will carry out a partial closure of these subloops within the main loop. For this purpose, the program will close all those points bearing the same name but internally identify whether it is indeed the same point due to a rod-comparison algorithm, by applying the corresponding tolerance margin. This means that if we give all levels the same name the program will identify which points coincide and which do not in order to close the subloops generated along the course.

• The names of the points observed do not require any particular order. Only in the event of one wanting to determine certain subloops will it be necessary for the point to have the same name. In this way, the program will assign the Partial Point quality.

• The compensation is carried out in proportion to the number of levels. • One can make a single large-scale loop or subdivide the loop when passing through

common points (Partial). The total error is unchanged, but the achievement of partial points allows us to close subloops where you can see the inherent errors of each subloop.

Study of Errors What follows is a study of the random errors that can take place during a trigonometric leveling process. This study shows the high precisions a Trigonometric Leveling process can have when using the Midpoint methodology – without having to take the height of the instrument. As can be seen in the study, the accuracies – which depend on the instrument type and the geometry of the level – can reach the level of the results of a Standard Geometric Leveling with the advantage of greatly improved performance. It is especially recommended for mountainous areas, where it can increase its performance fivefold.

Errors according to instrument In the following calculation example, we assume an average distance between sights of 100m – 200-m levels - and an average angle inclination of 5º with the use of autolock systems in all cases. NOTE!!: 5º represents an 8.75 % slope, that is, 8.75 m in a 100-m sight and therefore 17.50 m with a level. With 40 m levels, we would have a slope of 3.5 m, which is approximately the maximum slope to be considered with a sight and level).

Geometric Leveling According to the specifications of the DINI Electronic Level, taking 20-m levels into account we obtain: DiNI 0.7 mm (DINI 22) Invar precision bar code staff: ekm= 0.7 mm Standard bar code staff: ekm= 1.3 mm DiNI 0.3 mm (DINI 12T) Invar precision bar code staff: ekm= 0.3 mm Standard bar code staff: ekm= 1.0 mm In both cases, we take electronic measurement into account. What follows is a comparative graph of both systems, showing the obvious advantage represented by the use of High-Accuracy Trigonometric Leveling in relation to Geometric Leveling.
