What does the abbreviation 3DEP stand for?

The abbreviation 3DEP stands for The National 3D Elevation Project, which is a significant initiative in the United States aimed at acquiring high-quality, high-resolution, three-dimensional elevation data for the entire country. This project is crucial for various applications, including flood risk management, topographic mapping, and natural resources management. By providing comprehensive elevation data, 3DEP enhances scientific research, supports infrastructure planning, and improves community resilience against environmental hazards.

The other choices, while they incorporate elements related to elevation and 3D data, do not accurately represent the initiative's full scope or official title. The correct answer reflects a recognized national program designed to enhance the accessibility and usability of elevation data across various sectors, making it a vital component of geospatial and environmental considerations in the United States.
