Town Benchmarks

A benchmark is a known, fixed point of reference that is used to establish and maintain height (elevation) measurements for various surveying and mapping purposes. Benchmarks are critical in providing a consistent vertical reference point across different surveys and projects, and they help ensure accurate and standardized elevation measurements. 

In surveying, a benchmark is used as a starting point for measuring the elevation of other points or objects in the field. Benchmarks are critical for establishing height or elevation data for various purposes, such as land surveying, construction, topographic mapping, and noting land changes over time.
