Basemap Series
The data collected by several platforms is presented in the form of basemaps, with each map covering 2' of latitude and 4' of longitude. Data are gridded at a resolution of 2 metre. For perusal via the web portal, images are created in which depths are colour coded (based on the range of depths in the mapsheets) and the terrain is sun-illuminated. Grid files are available for download in ESRI grid format (.flt and .hdr files for each mapsheet, downloaded as a zipped .tgz archive file).
