Topo-bathy lidar acquisition and processing in the Mariana Islands covering Aguijan, Rota, Saipan, and Tinian. This product is a classified lidar point cloud data tiles in LAS 1.4 format, delivered in 500m x 500m tiles with FileSourceID set to 0, headers in OGC(2001) WKT, intensity normalized to 16-bit, and linear rescaling. Lidar is clipped to the extent of the area of interest for the topo-bathy data. Woolpert Inc. (Woolpert) was contracted for a two-part lidar data acquisition and lidar data processing effort in the Commonwealth of the Northern Mariana Islands. Part one required lidar data acquisition, initial data processing, and data coverage verification in the field performed under the United States Geological Survey (USGS). Part two is for the final data processing, derivative lidar products, and QA/QC and is performed under the NOAA Office of Coastal Management (NOAA) Contract. Woolpert collected lidar using their Hawkeye 4X topo-bathy lidar sensor, to provide high density topographic lidar to meet National Geospatial Program Lidar Base Specification Version 1.3 QL1 standard, while simultaneously acquiring bathymetric lidar data at National Coastal Mapping Strategy 1.0 QL2b standard. In addition to these lidar point data, the hydro-flattened and topobathy versions of the Digital Elevation Models (DEMs) created from the lidar point data, are also available. These data are available for custom download at the links provided in the URL section of this metadata record. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
