Y level or Wye-level consists y-shaped frames which supports the telescope. Telescope cane be removed from the y-shaped supports by releasing clamp screws provided. These y-shaped frames are arranged to vertical spindle which helps to cause the rotation of telescope.
The Y level, also known as the wye level, is the oldest and most bulky of the earlier optical instruments. A low-powered telescope is installed in a pair of clamp mounts, then levelled using a spirit level set parallel to the main telescope.
Levelling for Finding Distance above Earth (With Diagram)| Surveying. Article shared by: After reading this article you will learn about the levelling for finding distance above earth, explained with the help of suitable diagrams. Meaning of Levelling:
This handbook is intended to provide a practical guide for the undergraduate student at the School of Rural and Surveying Engineering at the National Technical University of Athens. Effort is made to have this handbook updated annually. 1. NATIONAL TECHNICAL UNIVERSITY OF ATHENS.
Introduction to surveying. Types of measurements (distances, directions, angles, height differences), units of measurement. Geographical Polar and Cartesian coordinates; basic calculations; determinations of coordinates, direction and distances; errors of measurements, sources and types of errors, significant digits.
Surveying procedures. Control points establishment (horizontal and vertical control networks), basics of topographic maps. Basics of vertical alignments and cross-sections.
Students will be able to manage all stages of the work leading to a complete surveying project at a professional level. The course also aims to develop critical thinking whereby students must address solutions to engineering problems that arise during a typical surveying project.
