Transit

Transits are instruments used in the fields of drafting, surveying, and mapping. They are part of the supply class of Drafting, Surveying, and Mapping Instruments, which falls under the supply group of Instruments and Laboratory Equipment.

Transits are optical instruments that are used to measure angles and distances in surveying and mapping applications. They typically consist of a telescope mounted on a tripod, with a rotating horizontal and vertical axis. The telescope allows for precise sighting and measurement of angles, while the rotating axis allows for accurate horizontal and vertical measurements.

Transits are commonly used in various industries, including construction, civil engineering, land surveying, and cartography. They are essential tools for accurately measuring and mapping land, determining property boundaries, and creating detailed topographic maps.

In addition to measuring angles and distances, transits may also include features such as leveling bubbles for determining horizontal and vertical alignment, vernier scales for precise measurements, and various attachments for mounting on tripods or other supports.

Overall, transits are crucial instruments in the field of drafting, surveying, and mapping, providing accurate and reliable measurements for a wide range of applications.
