Land surveyors need to take precise measurements with special equipment to find out the precise location of boundary lines, which is the starting point for almost every property development project. Land surveyors will use different processes, which will depend on what they need to do. For construction and engineering, property lines that identify the location of buildings and roads need to be studied. But in a geodetic survey, satellites and aerial imaging is used to measure large areas of land. Boundary or land surveys are used to determine the location of property lines, which can be useful for many development projects. Surveyors need to have the right equipment because it will ensure the most accurate results. And because it can measure both horizontal and vertical angles between points, a theodolite is considered to be the ultimate surveying tool.


Slope is calculated by finding the ratio of “vertical change” to the “horizontal change” between two points on the same line (called “rise over run”). This result is valued as a percentage and can be useful information in certain applications related to construction and engineering. Simply divide the vertical change by the horizontal change, and you’ll be able to determine the slope of a line.

Frequently Asked Questions

What does a plumb bob establish?

A plumb bob is a weight with a pointed tip on the bottom that’s hung from a string, and it’s used to establish a vertical reference (called a plumb line). It can be used to make sure that constructions are plumb, but it can also be used in surveying to establish the nadir with respect to gravity at a specific point.

How do I use a plumb bob?

To use a brass plumb bob, you must tie the string at the point that needs to be plumbed. The weight (or bob) can then be allowed to swing freely. And when it stops, its resting point will be precisely below the point from which the string has been fixed.

Why is there a hole at the tip of a plumb bob?

The hole on a brass plumb bob is where you'll attach the string, which can be fixed at a location in which you need to establish a vertical reference. It can be a simple hole, but it may also have a ring attachment or a removable threaded cap that will allow the string to hang from the center of the weight.

How long have plumb bobs been used?

Plumb bobs have been used since the beginning of human civilization. They were used by the Babylonians, the ancient Egyptians, as well as the ancient Greeks and Romans to get an accurate vertical reference while building structures or marking the location of stars and planets. Even now, they’re considered to be the most effective way to establish a vertical during construction.
