Introduction
Since the beginning of modern civilisation, the accurate measurement of length has been a key part of the growth and development of mankind. Many of the greatest engineering feats of man can be directly attributed to the advances in measurement technology and the methods used to obtain accurate values. One of the most efficient methods of measuring length is Plane Control Measurement (PCM) which has been in use since the mid-19th century.
What is Plane Control Measurement?
Plane Control Measurement (PCM) is a system of measurement used to accurately determine the length, width and height of an object or structure. The PCM technique is performed by placing three or more points in an area known as an area control grid and determining the distance between these points. By extrapolating the distances between these points, a value for the entire area can be calculated.
How is PCM Used Today?
Plane Control Measurement is most frequently used in engineering and surveying applications. It is especially useful in large construction projects where extremely detailed measurements are required such as in the building of highways or bridges. By using the PCM technique, engineers can gain a detailed understanding of the site and design the structure accordingly.
In addition to engineering and surveying, PCM is also used in other industries such as mining and aviation. It is often used for mining operations to determine the size and shape of ore deposits underground and for aviation to measure the runways at airports.
Advantages of Plane Control Measurement
One of the major benefits of using the PCM technique is that it is extremely accurate. Compared to traditional methods of measurement, the PCM technique can be much more accurate and can provide more detailed measurements. It is also faster than other methods as the entire process can be performed relatively quickly without sacrificing accuracy.
Additionally, the PCM technique is relatively simple to use and does not require a large amount of equipment. Most of the time, all that is needed is a set of measuring points which can be quickly and easily set up in a matter of minutes.
Conclusion
Plane Control Measurement is a highly accurate and efficient system of measuring length and width. It is often used in engineering and surveying applications, but is also beneficial in other industries such as mining and aviation. PCM is relatively simple to use and offers a number of advantages, making it one of the most reliable and accurate methods of determining length, width and height.
