Which NAMRIA branch is tasked with maintaining a national geodetic control network for surveying and mapping?

• A. Hydrography Branch
• B. Mapping and Geodesy Branch
• C. Geospatial Information System Management Branch
• D. Resource Mapping and Analysis Branch

Answer: (B)

Maintaining a national geodetic control network is a geodesy and mapping function. This network provides the precise reference points—benchmarks, triangulation stations, and GNSS control points—that underpin all surveying and mapmaking in the country. The Mapping and Geodesy Branch specializes in geodetic reference systems, coordinates, and the practical upkeep of this network, including field surveys, monument maintenance, and adjustments to keep the network accurate and consistent for all surveys and maps. The other branches focus on different areas: hydrography handles depth measurements and nautical charts; GIS management deals with the storage, sharing, and use of geospatial data; resource mapping and analysis concentrates on mapping and analyzing natural resources. None are primarily responsible for the national geodetic framework, so the one dedicated to mapping and geodesy is the best fit for this task.
