Opisometer is a measuring instrument used to determine distances on maps. The spelling of opisometer is "əʊˌpɪsɒmɪtə(r)". The 'o' is pronounced like the 'o' in 'go', and the 'i' sounds like the 'i' in 'sit'. The letter 's' is pronounced like the sound it makes in the word 'snake'. The 'm' sounds like the beginning of the word 'mother'. The last syllable is pronounced like 'meter'. The phonetic transcription makes it easier to understand the pronunciation of this complex word.
An opisometer is a mechanical or electronic device used for measuring distances on maps or diagrams. Also known as a map measurer or curvimeter, an opisometer is designed to provide accurate measurements of both straight and curved lines.
The opisometer typically consists of a small wheel or roller, connected to a calibrated dial or counter. To use the device, the user places the wheel on the starting point of the line to be measured and rolls it along the line while closely following its curves and bends. The dial or counter then displays the corresponding distance measurements as the wheel moves.
Opisometers are commonly utilized in various fields including cartography, urban planning, and engineering. They offer a convenient and efficient way to determine distances on maps or plans without the need for complicated mathematical calculations. Moreover, they can be used to measure distances on irregular or non-linear routes, making them highly versatile for diverse applications.
The invention of electronic opisometers has led to increased precision and ease of use in recent years. These modern devices often feature digital displays, buttons for specific functions, and the ability to switch between different units of measurement. This advancement has further improved the accuracy and efficiency of distance measuring processes in various professional industries.
The word "opisometer" is derived from the Greek words "opis" meaning "distance" and "metron" meaning "measure". Therefore, "opisometer" literally means "distance measure" in Greek.
