How do you calculate the horizontal distance in surveying?

What is the method of determining distance and elevation using instruments and geometry?
Surveying
What is a slope distance?
Surveying terminology. The measure of distance along a slope. The distance of a line where elevation changes from point 1 to point 2
Height of the building73m. its angle of elevation is 60deg at some specific point. what is the distance from that point?
65 m
What globe lines that are always the same distance apart?
"Parallels" of latitude. Those are the lines that are drawn horizontal on the globe or map.
When coordinates of two geographical points are known and we calculate the distance between them Is the calculated distance the horizontal distance or the actual distance?
The horizontal distance. Points of latitude and longitude can't account for elevation.
What is the change in elevation divide by distance?
The change in elevation divided by the distance traveled is known as the gradient or slope. It is commonly used to measure the steepness of inclines or declines along a route or terrain. The gradient is calculated by dividing the difference in elevation by the horizontal distance covered.
Measure of change in elevation in a certain distance is called what?
The measure of change in elevation in a certain distance is called slope. It is typically expressed as the ratio of the change in vertical height to the horizontal distance between two points on a surface.
How does a student calculate the gradient of a mountain stream?
To calculate the gradient of a mountain stream, a student can use the formula: gradient = (change in elevation) / (horizontal distance). First, they measure the elevation at two points along the stream, then find the difference between these elevations. Next, they measure the horizontal distance between the same two points. Finally, they divide the change in elevation by the horizontal distance to find the gradient, typically expressed as a ratio or percentage.
What is a high and low slope?
A high slope refers to a steep incline, meaning the elevation increases quickly over a short horizontal distance. A low slope, on the other hand, indicates a gentle incline with a gradual increase in elevation over a longer horizontal distance.
The ratio of the vertical distance to the horizontal distance?
The ratio of the vertical distance to the horizontal distance is sometimes colloquially phrased as "rise over run"; the numerically calculated value is called "slope". Mathematically, slope can be thought of as the tangent (function) of the "angle of elevation".
What is the acceptable floor slope for a building structure?
The acceptable floor slope for a building structure is typically between 1:50 and 1:100, which means for every 50 to 100 units of horizontal distance, there is a 1 unit rise in elevation. This slope helps with drainage and accessibility within the building.
What is trigonometric leveling?
It is the process of determining the differences of elevation of stations from observed vertical angle and known horizontal distance..
What are horizontal and slope distances in linear surveying?
In linear surveying, horizontal distance refers to the straight-line distance measured on a horizontal plane between two points, unaffected by elevation changes. Slope distance, on the other hand, is the actual distance measured along the slope between two points, accounting for the vertical elevation difference between them. The relationship between these two distances can be determined using trigonometric principles, particularly when the angle of elevation or depression is known. Understanding both distances is essential for accurate land measurement and mapping.
A building is 60ft high From a distance at A on the ground the angle of elevation to the top of the building is 40 From a lil nearer at B the angle of elevation is 70 Find the distance from A to B?
Using the formula: tangent = opposite/adjacent whereas tangent angle = height/ground distance, will help to solve the problem
What ia change in elevation divide by distance called?
The change in elevation divided by distance is called the "slope." It is commonly expressed as a ratio or a percentage, representing the steepness or incline of a surface. In mathematical terms, it can be calculated using the formula: slope = (change in elevation) / (horizontal distance). This concept is widely used in fields such as geography, engineering, and environmental science.
At a certain distance the angle of elevation to the top of a building is 60 From 40ft further back the angle of elevation is 45 Find the height of the building?
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
