New Jersey Statewide Elevation Data from Multiple LiDAR Projects

New Jersey elevation data consists of 18 discrete LiDAR collection projects covering overlapping subsections of the state. Projects were conducted over several years with differing technical specifications and include deliverables such as classified point clouds, digital elevation models, and contour lines. The data adheres to Federal Geographic Data Committee metadata standards.

Use Cases

• Generate high-resolution Digital Elevation Models (DEMs) based on the classified LiDAR point clouds.
• Create contour lines for topographic mapping based on the derivative data products.
• Analyze terrain changes over time based on the overlapping geographic extents of projects collected in different years.
• Conduct flood risk or watershed analysis based on the statewide elevation coverage.

Strengths

• Includes 18 distinct LiDAR collection projects, providing multiple data sources.
• Deliverables include multiple derivative products like DEMs and contour lines in addition to raw point clouds.
• Most metadata records adhere to the Federal Geographic Data Committee’s (FGDC) Content Standard.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
