What is the difference between the principle of Tacheometric survey and Totalstation survey?
The main difference is the method of measuring distances. Tacheometry is optical. A total station uses electromagnetic waves.
Distances measured using Tacheometry are determined by multiplying the difference in readings to a levelling staff between the upper and lower stadia hairs, by a constant (usually 100).
A Total station, by definition, is a theodolite with a built-in EDM measuring device. This sends out a signal of a known wavelength to a reflector and calculates the distance by measuring the time it takes for the signal to return.

SteveTacheometric surveying involves measuring horizontal and vertical distances using a stadia rod and a tacheometer, allowing for rapid data collection and calculations. Total station surveying, on the other hand, integrates electronic distance measurement (EDM) technology with a theodolite and other instruments to accurately measure angles, distances, and elevations more efficiently. Total stations offer faster and more precise data collection compared to traditional tacheometric methods.

What is principle of theodolite survey?
The principle of theodolite survey involves using a theodolite, a precision instrument with a rotating telescope, to measure horizontal and vertical angles in surveying and construction. By sighting through the telescope at specific points, surveyors can determine the angles and distances between objects, enabling accurate mapping and layout of land and structures. This tool is essential for precise measurements and alignment in construction projects.
What age group shows the greatest difference between males and females?
The teenage years typically show the greatest difference between males and females in terms of physical and psychological development. This can be attributed to the hormonal changes and growth spurts that occur during this period, leading to noticeable disparities between males and females in areas such as height, muscle mass, and emotional maturity.
What is significant difference?
A significant difference refers to a statistically meaningful distinction between two or more groups or variables. It implies that the difference observed is unlikely to have occurred by chance and is likely to have practical relevance. Statistical tests are used to determine if a difference is significant.
What is a statement of relationship between two or more concepts?
A statement of relationship between two or more concepts describes how the concepts are connected or interact with each other. It can highlight similarities, differences, dependencies, or impacts between the concepts to better understand their relationship and implications.
Can an infant tell the difference between its identical twin mother and aunt?
It is unlikely for an infant to tell the difference between its identical twin mother and aunt initially, as they share the same genetic makeup and may look very similar. However, over time the infant may start to recognize subtle differences in behavior, scent, or other cues that help differentiate between the two.
