The grid contained in the bathy_05m.zip file is available as an ESRI Binary grid and an ASCII grid with an ESRI header. However, the folder structure within bathy_05m.zip is critical to proper use of the ESRI binary grid.
To utilize these data, the user must have a GIS software package capable of reading ESRI Binary grids or ASCII grids with ESRI headers, or be able to manipulate an ASCII matrix with a geospatial header. The ASCII raster files can be easily converted to ESRI grid format in either ArcView with Spatial Analyst extension (Import Data Source: ASCII Raster) or ArcGIS with Spatial Analyst extension (ASCII to Raster). The user should select floating point grid (as opposed to integer grid) when converting the bathymetry data.
