Data were converted from xyz values without return numbers or time stamps. Point classifications have not been done. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. The purpose of this survey is to collect topographic lidar across the islands of Tinian, Rota, and Saipan to support the production of 2-foot contours, particularly in areas of airport infrastructure.

Scan lines can be seen in the landscape, suggesting there were issues with sensor calibration or alignment. Horizontal Positional Accuracy The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than 0.75 m (95% confidence). Vertical Positional Accuracy The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than 0.30 m (95% confidence) These data were collected using the CHARTS System 2, including the SHOALS 1000T SN:002 system. It is owned by the Naval Oceanographic Office (NAVO) and operated through contract. The system collects topographic lidar data at 10kHz and hydrographic data at 1kHz. An airborne hydrographic and topographic survey was conducted in the Commonwealth of the Northern Mariana Islands (CNMI) 20-24 March, 2006. This survey was conducted using Kinematic GPS positioning and all hydrographic and topographic data was collected with respect to the NAD83 ellipsoid. No new geodetic work was done in CNMI. The kinematic GPS base stations were established over NGS benchmarks. The aircraft was initially positioned using the published NGS DG3988 NAD83 position. In order to precisely position the base station in WGS84 the GPS datasets were submitted to NOAA’s Online Positioning User Service (OPUS). The positions provided by OPUS were then averaged. The final Saipan base station position used for final data processing is: N 15 degrees 13' 34.66282" E 145 degrees 44' 14.50749" WGS84 ellipsoid height: 58.041 meters The NOAA Office for Coastal Management (OCM) received files in txt format with longitute, latitude, and elevation in NAD83 ellipsoid heights. Saipan data were received in mean sea level (56.06 meters above the NAD83 ellipsoid). OCM performed the following processing on the data for storage and provisioning purposes within Digital Coast: 1. Saipan data were transformed to ellipsoid heights 2. Data were imported into LAZ format using txt2las. 2018-07-16T00:00:00 The LAStools lasground tool was used for automated point classification. Data were first tiled into 1 km squares in UTM projection with 20 meter buffers using lastile. Lasground was run on the tiles with the default settings and the buffers were removed. The data was reprojected to geographic coordinates for ingest. 2018-07-16T00:00:00 Office for Coastal Management processor Source Contribution: Lidar | Source Geospatial Form: globe | Type of Source Media: hard drive 2007 CNMI Saipan CHARTS Survey 2007-05-06 2007-05-09 The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2025-07-09NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
