-
Baseline: A precisely measured line that serves as a reference for a survey. It's the starting point from which other measurements are taken.
-
Benchmark: A permanent marker of known elevation, used as a reference point for vertical measurements. It's like a 'sea level' for your survey.
-
Coordinate: A set of numerical values that define the position of a point in a specific reference system (like latitude and longitude or a local grid). It's the 'address' of a point on the earth.
-
Datum: A reference surface or system used for calculating positions. Think of it as the foundation upon which all measurements are built.
-
Elevation: The vertical distance of a point above a reference datum, usually mean sea level. This is the height of a point.
-
GPS (Global Positioning System): A satellite-based navigation system that provides precise location data. Today, it's a critical tool for surveyors.
-
Leveling: The process of determining the elevation of points. This is used to determine the relative heights of points on the earth's surface.
-
Line of Sight: The unobstructed path between a surveying instrument and the target. Imagine a straight line from your eye to what you're looking at.
-
Offset: A measurement taken at a right angle to a survey line to locate a point.
-
Traverse: A series of connected lines whose lengths and directions are measured. It forms a framework for a survey.
-
Bearing: The horizontal angle between a line and a reference meridian (usually north or south). It is essential for determining direction.
Understanding these surveying definitions will provide a solid understanding of the terms. Now, you should have a solid grasp of these core concepts. Feeling good? Awesome! Let's move on to some more specific surveying terminology.
