Source Bathymetry: Mosaic of gridded multibeam bathymetry and bathymetry derived from multispectral IKONOS satellite imagery of Ofu and Olosega Islands, Territory of American Samoa, USA

Source DEM: National Elevation Dataset

Process: Elevation data (bathymetry and DEM) were mosaiced and gaps were filled by calculating focal mean from the surrounding cells. The mosaic tool and raster calculator of ArcGIS (version 9.3) by Esri were used to derive the product. Contour was derived from the mosaic bathymetry using the contour tool of ArcGIS (version 10.1) by Esri.
