What does HARN stand for?

HARN stands for High Accuracy Reference Network, which is a system of geodetic control points that provides precise positioning information for various applications, such as mapping and surveying. Established by agencies like the National Geodetic Survey (NGS) in the United States, HARN utilizes advanced measurement techniques and high-resolution data to ensure that the coordinates of points within the network are exceptionally accurate and consistent across large areas.

This network is particularly important for professionals requiring high-precision data, such as those working in GIS, cartography, and engineering, as it allows for reliable integration of spatial data from different sources. The term emphasizes the high level of accuracy achieved through the use of advanced technology and techniques in reference networks.

The other options do not accurately define HARN as they either describe different types of networks or do not reflect the specific terminology used in geodesy and surveying practices. Understanding the correct terminology ensures that professionals can communicate effectively and utilize the right systems for geographic data analysis and applications.
