| hasSummary |
-
ETOPO1 is a 1 arc-minute global relief model of Earth's surface that
integrates land topography and ocean bathymetry. It was built from
numerous global and regional data sets, and is available in "Ice
Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock"
(base of the ice sheets) versions. Data are available in two grid
registrations. For grid/node-registration, cells are centered on
lines of latitude and longitude (21601 by 10801 cells), and for
cell/pixel-registration, cell edges are along lines of latitude and
longitude (21600 by 10800 cells). The grid-registered is the
authoritative registration. The cell-registered is derived from the
grid-registered, and the conversion produces slightly flattened
relief.
