Colorado Land Surveyor Practice Exam

Which coordinate system is typically used in geodetic surveying?

1. Local coordinate system

2. National geodetic survey coordinate system

3. Global positioning system

4. Universal transverse Mercator

The correct answer is: National geodetic survey coordinate system

The national geodetic survey coordinate system is specifically designed to provide a framework for geodetic measurements and map-making throughout a country. This system is based on accurate measurements of the Earth's surface and provides a consistent set of reference points used for a variety of applications, including engineering, construction, and land-use planning. The use of a national geodetic system ensures that the data is standardized across different regions and can be accurately relied upon by surveyors and engineers when conducting their work. In contrast, a local coordinate system may vary from one area to another and lacks the standardized reliability of a national system. The global positioning system, while useful for determining position, operates based on satellite signals and does not provide the grid and reference framework necessary for detailed geodetic surveying. Likewise, the Universal Transverse Mercator coordinate system is widely used for mapping and navigation, but it does not encompass the broader scope and specific reference framework provided by a national geodetic survey system, making it less suitable for comprehensive geodetic surveying purposes.
