00:00:00 - 00:25:00

This video explains how to create longitudinal and transversal sections using level curves from a topographic survey. It also explains how to calculate slopes and slopes at intersections.

• 00:00:00 In this video, we learn how to create profiles and sections longitudinal and transversal by using curves of level from a topographic survey. The level curves can be obtained with either a fixed-level station or a total station. Hillman Azahar, an engineer civil, will be teaching this lesson. First, Hillman will show how to create a longitudinal profile and sections transversal from level curves of a planar terrain that was developed from a level survey using a simple and complex leveling system. Then, he will focus on this area of the ground, since it is the only one that is 50 x 50 meters in size. From this ground surface, Hillman will create a composite level using a multiple elevation system. Next, he will create a longitudinal profile of the terrain based on the elevations and cotas that he has placed along the axes. Finally, he will create a transversal section for this terrain based on the intersection of the lines of equal elevation.
• 00:05:00 This video explains how to draw a longitudinal section and transversal sections using a perforated sheet. The first step is to determine the location of the start point, and then draw perpendicular lines to the curves that intersect the longitudinal line. Next, draw the level curves and determine the elevations at each point. Finally, mark the parking areas.
• 00:10:00 In this video, the author discusses how to calculate slopes and slopes at intersections when creating a profile according to the level 100 curve. He explains that if the slope is greater than 99, the next one would be 98, 97, 96, and so on. When the last number reaches 95, the slope decreases and does not reach 96. He then goes on to explain what to do in this situation and how to generate profiles using civil cut or civil 3D. Afterwards, he shows how to calculate slope differences and how to determine the direction of gradients. He then shows how to calculate slope percentages and how it would apply to a specific area. He concludes the video by showing how to calculate slope percentages for a specific length and direction.
• 00:15:00 In this video, the presenter explains how to make a longitudinal profile, using elevation and sectional transversals. The topographical features should be clearly laid out to avoid future mistakes. The longitudinal profile or axis 1, 2, or 3 can be called depending on the number of profiles taken from a single piece of land. The parking areas always need to be clear in text, and large enough to be noticeable. The slopes in this example were placed to make the profile more complete and clear in the ground and soil. A shadow was also added to make the section more visible. The same technique can be used for other types of profiles, such as transversals. This video also covers sectional transversals, which are similar to longitudinal profiles, only on a smaller scale. 10 sections transversals should be taken, but I will focus on one here. I need to take the level curves that are being cut by the longitudinal line, and then I need to take the intersecting level curves. I will then take the length of the longitudinal line, divided by the number of intersecting curves, and that will be the length of the sectional transversal. I will then turn it around and look at it from the other side, so that it
• 00:20:00 In this video, we see how to create a longitudinal profile and transversal sections. The main point is to use a curve to intersect the level 100, 99, 98 grid. We then use the 98-99 curve to start and end the section. We then use 98-100 to connect the two. Finally, we add 101 to the end to make it an even 100. We then create a transversal section from 0-20 and scale it to be 10 meters wide on each side. We then use this to create a longitudinal profile for a parking lot.
• 00:25:00 This YouTube video provides a description of the perfil longitudinal and transversal sections of a graph. The video provides an overview of how these sections can be used to analyze data, and how they can be used to identify relationships between variables.
