Description
This data was collected by Woolpert using a Leica HawkEye 4X sensor. The data was acquired from 20221022 - 20221202. The data includes topobathy data in LAS 1.4 format classified as unclassified (1), ground (2), low noise (7), topo water surface (9), high noise (18), bathymetric point (40), bathymetric water surface (41), synthetic derived water surface (42), submerged object (43), International Hydrographic Organization (IHO) S-57 object (44), submerged aquatic vegetation (64), and bathymetric bottom temporal changes (65) in accordance with project specifications. The lidar data in ellipsoid heights was used to create the final topobathymetric DEMs in ellipsoid heights.
Lidar data classes 2, 40 and 43 were used to generate a raster in geotiff format, with 1 meter pixel resolution for the entire area. The raster was then clipped to the tile grid and named according to project specifications to result in tiled 5000m x 5000m topobathymetric DEMs. The project consists of approximately 53 square kilometers of data collected in Ofu-Olesega, American Samoa. This dataset contains 6 5000 m x 5000 m raster tiles.
