2008 NOAA LIDAR Topographic Data for New Hampshire Coast

NOAA National Geodetic Survey collected these LIDAR topographic data on June 8, 2008, using an OPTECH ALTM system. The NOAA Office for Coastal Management processed the data to bare earth and classified water points. The data is stored in LAS format files.

Use Cases

• Model coastal erosion and flooding based on bare earth topographic data.
• Analyze terrain elevation for infrastructure planning based on classified LIDAR points.
• Map water bodies and coastal features based on classified water points.
• Conduct change detection studies by comparing this 2008 LIDAR survey with newer data.

Strengths

• Data collected by NOAA's National Geodetic Survey, an authoritative source.
• Specific collection date of June 8, 2008, provides clear temporal reference.
• Processing details are provided, including bare earth classification and bridge removal.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
