LAND SURVEYING
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 MEASUREMENT
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.
