explain survey map plz !!!
Answers
Answer:
survey is a scientifically based method of measuring the surface of the earth to determine the horizontal distances, angles, and elevations of a particular area. The measurements are then typically plotted on a map.
Explanation:
Surveys are used to identify boundaries and features of land to determine ownership. They are employed in construction projects ranging from building fences to entire cities. In this lesson, you'll learn what a survey is and about the different types of surveys used today.
land survey defined
Meet Galvin, Terry, and Calvin, who are surveyors specializing in different types of surveys. A land survey, or simply survey, is the scientific process of measuring the dimensions of a particular area of the earth's surface, including its horizontal distances, directions, angles, and elevations. Artificial structures, such as a road or building, may also be noted on a survey. Once these measurements are taken, they can be used to make a map or even a globe. However, not all surveys are the same, so let's take a look at three major types.
Geodetic & Topographic Surveys
Geodetic Survey
Galvin takes geodetic surveys. A geodetic survey is one that involves the measurement of a very large area of the earth that must take into account the earth's curvature. Since they take into account the actual curvature of the earth, these surveys can be very accurate. Galvin's geodetic surveys are used as important references that other surveyors will use when surveying smaller areas of land, such as a typical farm or city lot.
