Disclosing a Dependable Guide to Topographic Survey
Is it easy to understand a land's features? Well, it isn't, and it takes a lot of hard work and research before a construction project begins. With the help of a topographic survey, you can know a lot of features of a plot. A topographic surveyor helps to determine the depth, size, and height of all the artificial and natural features on the land. These professionals can also recognize any changes in the contour of the land. Some of these natural features include:
Mountain
Valleys
Lakes
Rivers
Some of the artificial features are as follows:
Cities
Dam
Roads
History of Topographic Survey
The whole process of surveying and collecting data for the topographic survey started in the 1700s. This process was first created for military purposes and was later used mainly by the "Topographic Bureau of the Army." Later, the engineers used it to survey different features of the land.
Some Features It Can Recognize
A topographic surveyor can help examine many different features of the land. They can evaluate the height of an elevation such as a mountain. The information undergoes recording by referring to the sea level. It also helps to understand the latitude and longitude of a place. The former shows the position of a site by referring to the equator, while the degree from the Prime Meridian helps to measure the longitude.
Methods Used by Topographic Surveyors
There are several ways to gather information for topographic maps; two of the primary methods are:
Indirect Survey- This method gathers information about all the remote areas. Some of the things included in such practices are satellite pictures, radar, sonar and pictures taken from planes.
Direct Survey- In this method, a topographic surveyor uses surveying equipment to measure the elevations of the land. These experts utilize tools like clinometers and levels that can help to measure the land from the ground.
A Little About Topographic Maps
A topographic map is a detailed illustration of all the physical features of the land. Contour lines help show natural and artificial components. Some maps have numbers over the contour line to show the purpose of elevation.
The Usage of Topographic Survey
There are many different places where the best topographic surveyors are necessary. Some of these areas are:
The military was the first to use topographic surveys and still use them to plan their strategies.
Topography is also helpful for agriculture, which helps to understand how soil can be conserved and how water will flow over the land.
Many meteorologists also use it to get information about the mountain, oceans and valleys to predict the weather.
The data gathered by the topographic survey can help protect the environment from harmful elements. They are also used to build watersheds and wind blocks.
Topography in Recent Times
In the present-day scenario, the ways of collecting information have significantly changed. People get a more detailed survey because of the tools used today. Topographic surveyors collect a vast amount of data with the help of drones.
