Using NAMRIA Topographic Map as Base Map, the estimated boundary sketch of the project site is used for which purpose in geodetic design?

• A. Base Map
• B. Contour Map
• C. Road Map
• D. Satellite Images

Answer: (A)

The boundary sketch is used to establish the project limits on a base map, which provides the geographic framework for the geodetic design. Using the NAMRIA Topographic Map as the reference, the estimated boundary defines the extent of the area to be surveyed and designed, allowing you to plot the project’s limits accurately and align all control points and design elements within that framework. This base map serves as the horizontal reference layer for coordinates, features, and alignment, ensuring consistent positioning across the project.

It isn’t a contour map, which would focus on elevations and slopes; nor is it a road map showing transportation networks, or satellite imagery, which provides imagery data.
