2023-2024 NOAA NGS Topobathy Lidar: Ozarks area (Missouri, Arkansas and Oklahoma Rivers)

745 square statute miles of topobathymetric lidar data covering river sections in Missouri, Arkansas, and Oklahoma, collected from August 2023 to July 2024 by NV5 under contract for NOAA. The dataset includes point cloud data in LAS format with classifications for ground, water surface, bathymetric bottom, submerged aquatic vegetation, and other features according to ASPRS standards. Horizontal datum is NAD83 (2011) UTM 15, and vertical datum is GRS80 ellipsoid heights.

Use Cases

• Modeling river channel morphology and bathymetry based on classified point data for submerged topography and water column.
• Analyzing riparian zone and ground topography based on ground and bridge deck classifications.
• Mapping and monitoring submerged aquatic vegetation (SAV) based on the specific classification for SAV.
• Assessing seasonal changes or temporal exclusions based on classifications for identifiable snow and temporal exclusion.

Strengths

• Data covers a defined area of approximately 745 square statute miles.
• Points are classified to a detailed standard (ASPRS) with 15 distinct classes including bathymetric and aquatic features.
• Collection period is explicitly stated as August 2023 to July 2024.
• Spatial reference systems (NAD83, GRS80) and sensor channels (Chiroptera) are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
