What is the purpose of the National Geodetic Information System (GNIS) as described?

• A. Access to satellite imagery only
• B. Management and operational support to DENR and network users
• C. Cataloging of all land titles
• D. Weather forecasting data

Answer: (B)

The main idea is that GNIS is the centralized system that coordinates geodetic data and services for DENR and its field network. It is designed to provide management and operational support, ensuring that survey control data, coordinates, datum information, metadata, and related products are maintained, integrated, and accessible to authorized DENR staff and network users. This helps ensure consistency and reliability in mapping, land surveys, environmental monitoring, and other geospatial activities across DENR programs. It isn’t primarily about accessing satellite imagery, cataloging land titles, or supplying weather forecasting data, which is why those options don’t fit the described purpose.
