A change point in surveying refers to a specific location where there is a significant alteration in the characteristics of the terrain or features being measured, such as a shift in elevation, slope, or land use. These points are crucial for accurate data collection and analysis, as they help surveyors understand and document variations in the landscape. Identifying change points ensures that survey measurements are precise and reflective of the actual conditions on the ground.
A temporary benchmark in surveying is a reference point with a known elevation that is established for short-term use during a surveying project. It serves as a stable reference for measuring and determining the elevation of other points in the area. Unlike permanent benchmarks, which are intended for long-term use, temporary benchmarks are typically used for specific tasks and may be removed or disregarded once the project is completed. They are crucial for ensuring accuracy and consistency in level measurements during construction or land surveying activities.
A datum point is a fixed reference point used in various activities such as surveying, drafting, and engineering to establish a baseline or starting point for measurements and calculations. It helps ensure consistent and accurate results by providing a known reference for all measurements taken within a specific project or task.
Melting point is a physical property, not a change.
does the melting point of a substance change over time

In surveying, "IPOs" stands for "Initial Point of Survey." This refers to the starting point or reference point from which the survey measurements are taken. It marks the beginning of a survey project.
Radiation intersection traversing resection
HOT stands for Horizontal Offset Target, a reference point used in surveying to calculate horizontal measurements and distances from a particular point or feature.
Satellite surveying is a form of land survey that uses location information provided by the GPS satellite system to track the location of each reference point.

The Control Point Associates company is concerned with land surveying and consulting. They have offices in New Jersey, Pennsylvania and Massachusetts.
In surveying, backsight refers to sighting a previously established point in order to orient the instrument before taking new measurements. This helps ensure accuracy and consistency in surveying work by referencing known points.
Surveying terminology. The measure of distance along a slope. The distance of a line where elevation changes from point 1 to point 2
A fixed point on a map is a specific location with known coordinates that doesn't change. It serves as a reference point for navigation, cartography, and surveying purposes. Fixed points can include landmarks, monuments, or specific geographic features that are used to help orientate and locate other places on the map.
To conduct compass surveying, stand at a known point and sight the compass toward the new point whose direction you want to measure. Record the bearing shown on the compass. Repeat this process at multiple known points to triangulate the position of the new point. Calculate the coordinates of the new point based on the triangulated bearings and distances.
BM in surveying stands for "Bench Mark." It is a point of known elevation used as a reference for conducting leveling surveys. Bench Marks are typically physical markers installed in the ground or on a structure that serve as a consistent point of reference for determining elevations.
