This classified airborne LiDAR point cloud tile provides high-resolution elevation data for the Washington DC metropolitan area. The dataset consists of a classified airborne LiDAR point cloud tile captured as part of the USGS 3D Elevation Program (3DEP) Sandy Supplemental survey. It offers detailed topographical information for the National Capital Region, including ground elevation, vegetation, and structural features. As a technical resource, the file provides precise geospatial coordinates essential for large-scale site analysis and urban planning. The data is structured in the standard LAZ format, ensuring compatibility with professional GIS and point cloud processing software packages used for surveying, civil engineering, and environmental assessment projects.

The download is a 33.1 MB file containing .LAZ files.

Professionals can integrate this point cloud into GIS software or CAD platforms that support LAS/LAZ file formats. Users should verify the coordinate reference system and projection parameters upon import to ensure alignment with local project models. The data is commonly used to generate digital terrain models, extract site contours, or perform volumetric analysis for landscape design. It is recommended to use specialized point cloud management tools to clip, filter, or decimate the data before merging it into broader architectural or civil site plans.

This dataset is suitable for urban planners, civil engineers, and landscape architects working on infrastructure projects in the Washington DC area. It serves as a foundational reference for large-scale site development, flood risk assessment, and environmental impact studies during the early feasibility and master-planning stages. Designers often pair this data with satellite imagery or existing building footprints to create accurate site context models. The information is particularly valuable for projects requiring precise elevation data for complex site grading or urban infill analysis.
