LiDAR Data Sources:

Online LiDAR data sources other than the OpenTopography Portal - see the Data tab above for data hosted by OpenTopography

• USGS CLICK (Center for LIDAR Information Coordination and Knowledge) - a large collection of LiDAR point cloud data mostly in LAS format.
• National Center for Airborne Laser Mapping (NCALM) Data Distribution Center - high-resolution LiDAR DEM data collected by NCALM for National Science Foundation-funded research projects.
• Puget Sound LiDAR Consortium - high-resolution LiDAR data for western Washington.
• USGS Decision Support for Coastal Science and Management - LiDAR data of coastal and marine environments acquired by the USGS Coastal and Marine Geology Program.  Data includes coverage of many coastal National Parks, Monuments, Recreation Areas, and Historic Sites.
• NOAA LIDAR Data Retrieval Tool (LDART) - LiDAR coverage in narrow coastal swaths acquired mostly for topographic change mapping.  Point clouds and custom DEMs available.

Other Topographic Data Sources:

• USGS National Elevation Dataset (NED) - 1 arc-second (~30 meters), 1/3 arc-second (~10 meters), and some 1/9 arc-second (~3 meters) digital elevation model data via the USGS National Map Seamless Server.
• Shuttle Radar Topography Mission (SRTM) - 90 m DEM data available via CGIAR-CI.  30 and 90m SRTM data are also available via the USGS Seamless site
• ASTER Global Digital Elevation Map (GDEM) - 30 meter digital elevation model data created by stereo-correlation of ASTER VNIR images.
• NOAA National Geophysical Data Center Global Land 1 km Base DEM - “A 30-arc-second (1-km) gridded, quality-controlled global Digital Elevation Model (DEM)”
• NOAA National Geophysical Data Center ETOPO1 Global Relief Model - “ETOPO1 is a 1 arc-minute global relief model of Earth’s surface that integrates land topography and ocean bathymetry.”
