Infrared Electronic Distance Measuring Surveying Instrument

Infrared Electronic Distance Measuring (EDM) Surveying Instruments are devices used in surveying and mapping to measure distances accurately. These instruments utilize infrared technology to calculate the distance between the instrument and a target point.

EDM instruments typically consist of a telescope, a laser or infrared beam emitter, and a receiver. The instrument emits a beam towards the target, and the receiver detects the reflected beam. By measuring the time it takes for the beam to travel to the target and back, the instrument can calculate the distance.

These instruments are commonly used in various surveying applications, such as land surveying, construction, and civil engineering. They provide precise measurements, allowing surveyors to accurately determine distances between points on the ground.

Mapping Instruments, Surveying Drafting, on the other hand, refer to a broader category of instruments used in surveying and mapping activities. This category includes instruments such as theodolites, total stations, GPS receivers, levels, and drafting tools.

Theodolites are optical instruments used to measure horizontal and vertical angles in surveying. Total stations combine the functions of a theodolite and an EDM instrument, allowing for simultaneous angle and distance measurements.

GPS receivers use signals from satellites to determine precise positions on the Earth's surface. Levels are used to measure height differences between points, while drafting tools are used for drawing and creating accurate maps and plans.

All these instruments are essential for conducting surveys, mapping, and drafting activities in various industries, including construction, engineering, and land development.

In summary, Infrared Electronic Distance Measuring Surveying Instruments are a specific type of instrument used in surveying to measure distances accurately. Mapping Instruments, Surveying Drafting, is a broader category that includes various instruments used in surveying and mapping activities. Both types of instruments are crucial for conducting accurate surveys and creating detailed maps and plans.
